Important: #79005 - Included missing support for persistent connection in Redis cache backend 

See forge#79005

Description 

phpredis has support for persistent connections, but until now the Redis cache backend had the regular connect call hard-coded. For unknown reasons this is the only connection setting missing from the Redis cache backend but has now been implemented.

The configuration setting is named persistentConnection. It is an optional boolean option.

For other configuration options see https://docs.typo3.org/typo3cms/CoreApiReference/CachingFramework/FrontendsBackends/Index.html#redis-backend

Impact 

None. Non-persistent connections remain the default.
