Provide support for Workload Identity on Azure Redis Cache

[bcouavoux]

Proposal

Hello,

The Redis Cache service on azure has recently been made compatible with Entra authentication, making it possible to grant authorizations with workload identity.

We tried to create a TriggerAuthentication and use it in our scaleObject but without success. We get the error that Redis needs a password to connect and that the NOAUTH is not authorized.

This works fine for the Azure servicebus, but technically speaking, we need to use the redis lists and not the servicebus lists.
