feat: [AAP-46540] Remove redis from operator

[kaiokmo]

https://issues.redhat.com/browse/AAP-46540

This completely removes the deployment of redis from the operator (CSV, CRD, eda role, and deletes the redis role).

Adding upgrade cleanup tasks (to the eda role), and documentation updates will be done by different changes (AAP-59028 and AAP-59027).
