* Copy Cluster Client, Commands, Commands Parser, Tests for asyncio
* Async Cluster Tests: Async/Await
* Add Async RedisCluster
* cluster: use ERRORS_ALLOW_RETRY from self.__class__
* async_cluster: rework redis_connection, initialize, & close
- move redis_connection from NodesManager to ClusterNode & handle all related logic in ClusterNode class
- use Locks while initializing or closing
- in case of error, close connections instead of instantly reinitializing
- create ResourceWarning instead of manually deleting client object
- use asyncio.gather to run commands/initialize/close in parallel
- inline single use functions
- fix test_acl_log for py3.6
* async_cluster: add types
* async_cluster: add docs
* docs: update sphinx & add sphinx_autodoc_typehints
* async_cluster: move TargetNodesT to cluster module
* async_cluster/commands: inherit commands from sync class if possible
* async_cluster: add benchmark script with aredis & aioredis-cluster
* async_cluster: remove logging
* async_cluster: inline functions
* async_cluster: manage Connection instead of Redis Client
* async_cluster/commands: optimize parser
* async_cluster: use ensure_future & generators for gather
* async_conn: optimize
* async_cluster: optimize determine_slot
* async_cluster: optimize determine_nodes
* async_cluster/parser: optimize _get_moveable_keys
* async_cluster: inlined check_slots_coverage
* async_cluster: update docstrings
* async_cluster: add concurrent test & use read_response/_update_moved_slots without lock

@akx Thank you so much for this! Thanks again for introducing me to a new tool that I'm sliding into my workflow as well.

Remove support for end-of-life Python 2.7
Python 2.7 is end of life. It is no longer receiving bug fixes,
including for security issues. Python 2.7 went EOL on 2020-01-01. For
additional details on support Python versions, see:
Supported: https://devguide.python.org/#status-of-python-branches
EOL: https://devguide.python.org/devcycle/#end-of-life-branches
Removing support for EOL Pythons will reduce testing and maintenance
resources while allowing the library to move towards a modern Python 3
style. Python 2.7 users can continue to use the previous version of
redis-py.
Was able to simplify the code:
- Removed redis._compat module
- Removed __future__ imports
- Removed object from class definition (all classes are new style)
- Removed long (Python 3 unified numeric types)
- Removed deprecated __nonzero__ method
- Use simpler Python 3 super() syntax
- Use unified OSError exception
- Use yield from syntax

flake8 catches a wider net of mistakes than pycodestyle and is more
commonly used by the larger community. For example, it catches unused
imports, a few of which existed. These have since been removed.
Two "noqa" comments were added. One ignores the _compat.py file as it
has a large amount of Python version specific code. The second is in
utils.py which intentionally does not use an import.

Use the "as" keyword to capture the exception in a variable instead of
sys.exc_info().
Re-raise exception with the bare "raise" syntax.
Avoid "# noqa: E722" by catching BaseException, which includes all
exceptions including SystemExit.

Now matches the parent class signature. Running the benchmark previously
failed with the error:
TypeError: send_packed_command() got an unexpected keyword argument 'check_health'

redis-py maintained backwards compatibility by keeping the old "Redis"
class around for quite some time. While no doubt a convenience for folks
who relied on it, the presence of both Redis and StrictRedis causes
a number of support issues and general confusion. With 3.0, we're
breaking a few things to make redis-py better going forward.
This change removes the old Redis class. We also renamed the StrictRedis
class to Redis and aliased StrictRedis to Redis. For people that have
been using StrictRedis, this should not change anything. You can continue
doing things as you are.
People still using the legacy Redis class will need to update the argument
order for the SETEX, LREM and ZADD commands. Additionally, the return values
for TTL and PTTL now return the integer values -1 when a key exists but
has no expire time and -2 when a key does not exist. Previously these
cases returned a None value in the Redis class.

Remove workaround for handling unicode with older Pythons.

All Python versions can handled ordered placeholders.

The Token class now contains a cache of tokens, and each token stores its encoded value.
In Python 3 this prevents encoding the Token commands (get, set, incr, etc...) repeatly.
There is also a smaller performance improvement by creating fewer objects.
A very basic benchmark script was also added.
