This MR fixes the behavior of
`omni.isaac.orbit.sim.SimulationCfg.shutdown_app_on_stop` to not close
the app when the flag is False. Earlier, it would throw an error
(invalid physics handles) when the stop button was pressed in the GUI
and the flag was False.

# Description

Previously, while the manager classes supported "functional" class
terms, they only implemented `__call__` attribute. However, more
frequently, the class terms will keep some history in them which we
would want to clear out.

This MR introduces a `ManagerTerm` class for class terms which serves as
a protocol for how manager terms that are classes should be implemented.
The `ActionTerm` inherits from this `ManagerTerm`.

# Description

To resolve all environment indices, the previous implementation used
`self._ALL_INDICES`. However, this is not broadcastable when tensors are
indexed with two lists, for example:

```python
import torch

x = torch.zeros(100, 25)
x[[0, 2, 3, 4], [1, 2, 3]]
```

This MR fixes this bug (introduced in #248).

# Description

Previously, the `Asset` classes assumed that the root prim existed at
the spawn prim location. This means that when the robot is spawned at
`/World/Robot`, the articulation root prim is also at `/World/Root`.
However, this is not safe operation as many assets will have the root
defined under the spawn location.

The MR safely checks if there are prims under the spawn location that
have the API defined for them. If they do, then it uses that prim path
for initializing the views.

# Description

This MR makes a critical fix for the assets classes `reset` mechanism.
Particularly, the `write_` methods for the physics handles.

Before, the root and joint states were reset for all environments rather
than the specific `env_ids` concerned with the reset. This caused
instabilities in the dynamics, but it was not necessarily perceivable in
environments with spread-out resets like ANYmal.

# Description

The current `omni.isaac.orbit.envs.BaseEnv` does not include the methods
to `reset` and `step`, while the `RLTaskEnv` adds those functionalities.
This PR unifies the structure of an `Env` and adds these core components
to the `BaseEnv` as well.

# Description

This MR changes the `AssetBase` and `SensorBase` classes to use
time-line events instead of physics events for initializing and
invalidating physics-based handles. This is needed for cases where we
have to wait for physics mesh cooking to finish before the handles are
available.

For instance, with the previous code, when trying to initialize the
views for deformable objects, the following error happens:

```bash
2023-11-11 00:18:06 [17,966ms] [Error] [omni.physx.plugin] Cuda context manager error, simulation will be stopped and new cuda context manager will be created.

# Description

Earlier we were copying the whole `ArticulationView.initialize()` method
from Isaac Sim since it doesn't work with our initialization callback
hooks. Since this was bulking up the code and requires us to keep
duplicating their function, this MR replaces the current fix with some
tricks that work in a less bulky way.

Additionally, the MR fixes the property name `default_root_state_w` to
`default_root_state` since the latter is more correct (environment
origin instead of world origin).

Currently, we are downgrading many libraries to be able to use the Gym

This MR upgrades the repository to use the Gymnasium Environment class.

This MR fixes the test scripts inside the `omni.isaac.orbit_tasks`

to latest changes in the core framework.

Additionally, the tests helped in realizing that the environment did not
close properly, i.e. some managers do not get destroyed properly and
still hold references to certain scene entities. The MR now explicitly
calls all `del` operators over all the managers to delete them in the
right-order.

# Description

The null-command generator class sets the resampling time as
`(-math.inf, math.inf)`. However, on execution, the random ampler does
not like this range and throws a RuntimeError as the operation becomes
out of bounds for float.

To deal with this issue, the MR just overrides all the functions of the
base class and leaves them "empty".

# Description

This MR does the following:

* Changes the way environment and agent configs are handled. These are
now moved to their respective `env` folder.
* Replaces YAML file with configclasses for rsl_rl library
* Adds examples of other robots for locomotion-velocity task: anymal-b,
unitree-a1, and anymal-d (placeholder)

The new environment folder structure is as follows:

```
my_task (folder)
   |- mdp  (folder where all user's task-specific terms are stored)
   |- config
       |- robot_name_1  (folder)
            |- robot_specific_env_cfg.py
            | agents (folder)
                |- rsl_rl_cfg.py
                |- sb3_cfg.py
                |- ....
            |- __init__.py (register robot-specific tasks)
       |- robot_name_2 (folder)  
   |- my_task_env_cfg.py (base env config)
   |- my_task_env.py (base env -- optional -- should normally use RLEnv)

# Description

With at least Isaac Sim 2023.1 (not checked on 2022.2.1), the URDF
importer from Isaac Sim seems to save the material paths as absolute
when trying to save the asset in its instanceable format. The material
paths are relative when the USD is generated as non-instanceable.

This MR fixes this behavior by adding a post-processing step that
iterates over the instanced mesh file and resolves all paths to become
relative.

You can use the tool by running the following:

```bash
./orbit.sh -p source/tools/convert_urdf.py ~/git/anymal_d_simple_description/urdf/anymal.urdf source/extensions/omni.isaac.orbit_assets/data/Robots/ANYbotics/ANYmalD/anymal_instanceable.usda --merge-joints --make-instanceable

This MR fixes the color of the ground in Orbit. It is now black since we
like that color more.

It also fixes the setting of the translation of the ground plane.
Earlier, it was taking z height from the configuration. Instead, now it
expects to get the full translation as an argument to its function. This
is needed to make it consistent with interactive scene designing API.

# Description

This MR does the following:

* Fixed the unit tests under `sim`

# Description
Adds in a new `Sensor` that performs frame transforms.

No tests as part of this initial PR as this feature is needed by
developers. Tests will be added in with the improvements:

# Description

When having agent-environment interaction, it is important to ensure
that PyTorch constructs no computational graph. Otherwise, it will keep
allocating memory for gradients and result in out-of-memory error.

This MR wraps all scripts with `torch.inference_mode()` to prevent this
issue.

# Description

This MR implements a long-awaited feature of separating out the UI and
UI-related operations outside the environment class.

The user can also set the UI window class themselves through the
configuration. This makes the UI window modular and provides more
freedom for future additions.

## Type of change

- New feature (non-breaking change which adds functionality)

## Screenshots

Also updated the GUI with various functionalities. This was kind of the
motivation to separate out the UI into a different window.

# Description

Earlier the UI was disabling buttons for which the config object set
`debug_vis` flag as False. This wasn't an elegant behavior as users may
want to enable the visualization from the GUI at runtime. This MR
modifies the behavior of all classes that provide debug visualization to
support this behavior.

# Description

Meshes such as "box", "cylinder" and "cone" are defined in
`omni.isaac.orbit.terrains.trimesh.utils.py` and can be used in configs
such as
[here](https://github.com/isaac-orbit/orbit/blob/17fc724de7386c919f6f0367980c1d8e9855c446/extensions/omni.isaac.orbit/omni/isaac/orbit/terrains/trimesh/mesh_terrains_cfg.py#L187).
In the example, their definition as a string is allowed but as they are
not explicitly imported, the general statement cannot capture the
missing functions. This PR makes sure that all mesh helper functions in
`utils.py` are imported and that the string format can be used.

# Description

As discussed in the past, the `BaseEnv` should only contain an
observation-action interface, while `RlEnv` should contain also the
task-specific interface. Based on this, the MR introduces the following
changes:

* Moves randomization manager to the `BaseEnv` class with the default
settings to reset the scene to the defaults specified in the
configurations of assets.
* Moves command generator to `RlEnv` class
* Adds a `NullCommandGenerator` for no command environments: This is
easier to work with than having checks for None.

## Type of change

functionality to not work as expected)
