Support lettuce ClientResources [DATAREDIS-462]

[spring-projects-issues]

Mark Paluch opened DATAREDIS-462 and commented

Add support for reusable ClientResources of the lettuce driver.

ClientResources allow to reuse the netty EventLoopGroup s across multiple client instances (similar to the Couchbase Environment). This change requires lettuce 3.4+ as the API was introduced with lettuce 3.4.Final. Spring Data Redis cannot be used with lettuce 3.3 and earlier after this change
