Overview

A new feature named redis-dp-session has been added, as well as the logic for accepting the deadpool-redis library in the redis-rs file, since deadpool-redis uses redis-rs in under the hood, so both are compatible and instead of duplicating, some attributes have been added to control the compilation of the features that are selected.

The doc tests workflow is failing because there is an example code in redis_rs in the Deadpool Redis section, but ins't marked only for the feature redis-dp-session, is there any way to control this so that the workflow succeeds?
