This change updates the benchmarking utilities to follow new module
naming for Isaac Sim 4.5. In addition, hydra support is added for the
benchmark scripts to allow modifications of config parameters via
command line. Hydra config parsing utilities are updated to allow for
missing agent configurations when benchmarking non-RL workflows.
