WIP: Implement TLS for Redis

[Nico-dl05]

Motivation

This PR aims to implement the TLS for Redis and improving the handling of dependencies between the submitter and redis.

Description

• TLS Implementation:
  • Added support for secure connections to Redis using TLS.
  • Configured Redis to use certificates for authentication (ca.pem, redis.crt, redis.key).
• Generic Callback for TLS:
  • Created a generic mechanism to handle TLS configuration and callbacks during deployment.
• Wait for Redis:
  • Implemented a conditional wait_for_redis mechanism to ensure that Redis is fully initialized before the Submitter starts.
  • Dynamically adjusts dependencies and paths based on the environment (local or CI).
• Mounting Redis Certificates:
  • Added conditional mounts for Redis certificates, ensuring secure communication between the Submitter and Redis.

Testing

• Verified container initialization and deployement in local environnement
• Ran HtcMock tests to ensure proper communication between Redis and the Submitter

Impact

• TLS implemented:
• Behavioral Changes: Ensures Submitter does not start until Redis is ready.

Additional Information

This is a work in progress, and further tests / fixes and optimizations are ongoing.
