### Feature Request: Add SSL Support for Redis in Celery

[ThomaciousD]

Description:
This issue is a follow-up to PR #2226 which introduced the use of Redis as a broker and backend for Celery.

To ensure secure communication between Celery and Redis, I propose adding support for Redis connections over SSL. This will be particularly useful in production environments where security is paramount.

Proposed Changes:

• Introduce new environment variables: REDIS_SSL, REDIS_SSL_CERT_REQS, and REDIS_SSL_CA_CERTS to allow SSL configuration for Redis.
• Modify Celery configuration to dynamically include SSL parameters in the Redis URL when REDIS_SSL is enabled.

Context:
This enhancement builds upon the work done in PR #2226, ensuring secure Redis connections in environments that require SSL.
