Optimize Redis integration tests

This commit ensures that Redis Testcontainers used for integration testing are managed by Spring to ensure proper ordering on shutdown.

Previously, Redis Testcontainer was closed before LettuceConnectionFactory which caused pending commands to hang and added a lot of wait to project build.

Closes gh-1086
