Add environment manager for parallel environments (#2209 )

Previously in v0.8 we added parallel environments via the
SubprocessUnityEnvironment, which exposed the same abstraction as
UnityEnvironment while actually wrapping many parallel environments
via subprocesses.

Wrapping many environments with the same interface as a single
environment had some downsides, however:
* Ordering needed to be preserved for agents across different envs,
  complicating the SubprocessEnvironment logic
* Asynchronous environments with steps taken out of sync with the
  trainer aren't viable with the Environment abstraction

This PR introduces a new EnvManager abstraction which exposes a
reduced subset of the UnityEnvironment abstraction and a
SubprocessEnvManager implementation which replaces the
SubprocessUnityEnvironment.

Fix flake8 import warnings (#2584 )

We have been ignoring unused imports and star imports via flake8. These are
both bad practice and grow over time without automated checking.  This
commit attempts to fix all existing import errors and add back the corresponding
flake8 checks.
