* 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 Tune tests have
been moved to python 3.7
* fix tune test_sampler::testSampleBoundsAx
* fix re-install ray for py3.7 tests

* Added fixes to CartPole example
* Apply suggestions from code review

## Why are these changes needed?
If an actor failover is triggered, but the RPC connection between the caller and the crashed actor instance is not disconnected automatically, subsequent tasks to the new actor instance may not be executed. The root cause is that the sequence numbers of tasks sent to the new actor instance is not starting from 0. Details can be found in #14727.
This PR fixes it by ensuring all inflight actor tasks fail immediately when actor failover is detected (via actor state notifications).

When gcs broad cast node resource change, raylet will use that to update local node as well which will lead to local node instance and nodes_ inconsistent.
1. local node has used all some pg resource
2. gcs broadcast node resources
3. local node now have resources
4. scheduler picks local node
5. local node can't schedule the task
6. since there is only one type of job and local nodes hasn't finished any tasks so it'll go to step 4 ==> hangs

This PR includes a script for building wheels for Macs with M1 processors. It roughly follows the pattern of the other scripts with a few differences.
Manually installs nvm
Uses miniforge conda to install python/pip instead of python foundation .pkgs
Doesn't pin numpy (we probably shouldn't be pinning it in the other scripts either...)
Commit detection falls back to git instead of erroring
All of these changes were made so that the script works on a laptop, which comes with a subset of the dependencies that the x86 buildkite image comes with.
## Why are these changes needed?
Prior to this PR, we have:
```cpp
class XxxAccessor {}
class ServiceBasedXxxAccessor : public XxxAccessor{}
class GcsClient {}
class ServiceBasedGcsClient : public GcsClient{}
```
However, XxxAccessor has only one implementation: ServiceBasedXxxAccessor. And GcsClient has only one implementation: ServiceBasedGcsClient.
I think this abstraction is not necessary and will make development hard(I have to modify two files every time).
This PR removes all ServiceBasedXxx and moves its implementations to the base class.
Now we only have:
```cpp
class XxxAccessor {}
class GcsClient {}
```
