azd pipeline config support for different branches

[weikanglim]

As a user, I should be able to run azd pipeline config to configure the Azure connection for different branches. The branch-specific behavior may be specific to federated credentials.

I want to be able to do this to configure CD for my mainline branch that is not main, or potentially other release servicing branches.

My 2 cents:
Let azd to be an example for how to set up a reference pipeline, but not as the tool you need to use for setting up all your pipelines.
In this case, for example, supporting multiple branches would require to create a group of secrets per branch so I could use azd for 3 different branches and each pipeline could have its own env values (secrets). This complicates things IMO.

I would like azd to help me create the FIC for the branches I want the action to run on. It could look at my default gh action, see which branches I have listed there, and then create FICs for each branch. As it is now, I need to figure out how to create my own FIC.

@weikanglim / @jongio - I believe this PR #2468 should solve the concern / issue here.
