## Why are these changes needed?
Since we are using gcs client as kv backend, we need to make it auto-reconnect in case of a failure. This PR adds this feature.
This PR adds auto_reconnect decorator to gcs-utils and in case of a failure it'll try to reconnect to gcs until it succeeds.
This feature right now support redis which should be deleted later once we finished bootstrap since kv will always go to gcs.

## Why are these changes needed?
This change adds Python publisher and subscriber in `gcs_utils.py`, and GRPC handler on GCS for publishing iva GCS. Error info is migrated to use the GCS-based pubsub, if feature flag `RAY_gcs_grpc_based_pubsub=true`.
Also, add a `--gcs-address` flag to some Python processes. It is not set anywhere yet, but will be set aftering Redis-less bootstrapping work.
Unit tests are added for the Python publisher and subscriber. Migrated error info publishers and subscribers are tested with existing unit tests, e.g. tests calling `ray._private.test_utils.get_error_message()` to ensure error info is published.
GCS based pubsub has gaps in handling deadline, cancelled requests and GCS restarts. So 3 more unit tests are disabled in the `HA GCS` mode. They will be addressed in a separate change.

* Fix QMix, SAC, and MADDPA too.
* Unpin gym and deprecate pendulum v0
Many tests in rllib depended on pendulum v0,
however in gym 0.21, pendulum v0 was deprecated
in favor of pendulum v1. This may change reward
thresholds, so will have to potentially rerun
all of the pendulum v1 benchmarks, or use another
environment in favor. The same applies to frozen
lake v0 and frozen lake v1
Lastly, all of the RLlib tests and have
been moved to python 3.7
* Add gym installation based on python version.
Pin python<= 3.6 to gym 0.19 due to install
issues with atari roms in gym 0.20
* Reformatting
* Fixing tests
* Move atari-py install conditional to req.txt
* migrate to new ale install method
