Add support for username based ACL for Redis

[Veera93]

Is your feature request related to a problem? Please describe.
In the current version of Orkes, the Redis configuration only allows for password-based authentication. However, starting from Redis version 6.0.0, support for ACL (Access Control List) with both username and password was introduced. Can we consider adding username support to the configuration?

Describe the solution you'd like
Jedis library already has the support for username and password-based configuration. We can wire the username in the properties and default it to null if the username is not configured.

I can create the PR, if I get the approval for this issue.
