Bump redis from 2.10.6 to 3.4.0

[dependabot-preview]

Bumps redis from 2.10.6 to 3.4.0.

Changelog

Sourced from redis's changelog.

• 3.4.0
  • Allow empty pipelines to be executed if there are WATCHed keys. This is a convenient way to test if any of the watched keys changed without actually running any other commands. Thanks @brianmaissy. #1233, #1234
  • Removed support for end of life Python 3.4.
  • Added support for all ACL commands in Redis 6. Thanks @IAmATeaPot418 for helping.
  • Pipeline instances now always evaluate to True. Prior to this change, pipeline instances relied on len for boolean evaluation which meant that pipelines with no commands on the stack would be considered False. #994
  • Client instances and Connection pools now support a 'client_name' argument. If supplied, all connections created will call CLIENT SETNAME as soon as the connection is opened. Thanks to @Habbie for supplying the basis of this change. #802
  • Added the 'ssl_check_hostname' argument to specify whether SSL connections should require the server hostname to match the hostname specified in the SSL cert. By default 'ssl_check_hostname' is False for backwards compatibility. #1196
  • Slightly optimized command packing. Thanks @Deneby67. #1255
  • Added support for the TYPE argument to SCAN. Thanks @netocp. #1220
  • Better thread and fork safety in ConnectionPool and BlockingConnectionPool. Added better locking to synchronize critical sections rather than relying on CPython-specific implementation details relating to atomic operations. Adjusted how the pools identify and deal with a fork. Added a ChildDeadlockedError exception that is raised by child processes in the very unlikely chance that a deadlock is encountered. Thanks @gmbnomis, @mdellweg, @yht804421715. #1270, #1138, #1178, #906, #1262
• 3.3.11
  • Further fix for the SSLError -> TimeoutError mapping to work on obscure releases of Python 2.7.
• 3.3.10
  • Fixed a potential error handling bug for the SSLError -> TimeoutError mapping introduced in 3.3.9. Thanks @zbristow. #1224
• 3.3.9
  • Mapped Python 2.7 SSLError to TimeoutError where appropriate. Timeouts should now consistently raise TimeoutErrors on Python 2.7 for both unsecured and secured connections. Thanks @zbristow. #1222
• 3.3.8
  • Fixed MONITOR parsing to properly parse IPv6 client addresses, unix socket connections and commands issued from Lua. Thanks @kukey. #1201
• 3.3.7
  • Fixed a regression introduced in 3.3.0 where socket.error exceptions (or subclasses) could potentially be raised instead of redis.exceptions.ConnectionError. #1202
• 3.3.6
  • Fixed a regression in 3.3.5 that caused PubSub.get_message() to raise a socket.timeout exception when passing a timeout value. #1200

Will need to get redis setup locally and test
