The user should be able to specify the external config repo branch

[luizbafilho]

Short description
As a User I want to be able to specify the external repo branch.

If the app repo and the config repo have different default branches currently wego breaks because it will use whatever was specified for the app repo. ie: you app repo uses main your config repo uses master.

We currently already check the default branch of the external config repo.

Users will want to open a PR to a specific topic or environment branch.

Acceptance criteria

• the user can have the app repo and the config repo with different branch
• the add command accepts the --app-config-branch

• Design diagrams
• WEP

New directory structure work might negate this as a valid feature.
