* first pass at ars, replicates initial results, still needs more testing, cleanup
* add a few docs and tests, bugfixes for ARS
* debug and comment
* break out dump logs
* rollback so there are now predict workers, some refactoring
* remove callback from self, remove torch multiprocessing

* Feat: adding TRPO algorithm (WIP)
WIP - Trust Region Policy Algorithm
Currently the Hessian vector product is not working (see inline comments for more detail)
* Feat: adding TRPO algorithm (WIP)
Adding no_grad block for the line search
Additional assert in the conjugate solver to help debugging
* Feat: adding TRPO algorithm (WIP)
- Adding ActorCriticPolicy.get_distribution
- Using the Distribution object to compute the KL divergence
- Checking for objective improvement in the line search

Critic updates
* Feat: adding TRPO algorithm (WIP)
Changes around the alpha of the line search
Adding TRPO to __init__ files
* feat: TRPO - addressing PR comments
- renaming cg_solver to conjugate_gradient_solver and renaming parameter Avp_fun to matrix_vector_dot_func + docstring
- extra comments + better variable names in trpo.py
- defining a method for the hessian vector product instead of an inline function
- fix registering correct policies for TRPO and using correct policy base in constructor
* refactor: TRPO - policier
- refactoring sb3_contrib.common.policies to reuse as much code as possible from sb3
* feat: using updated ActorCriticPolicy from SB3
- get_distribution will be added directly to the SB3 version of ActorCriticPolicy, this commit reflects this
