Adding the git_branching option

[Odilhao]

This will be used for pulpcore branching, the --commit make it hard to push/sync during branching, when we have at least 25+ package updates.

For this I'm adding a --branching to keep all commits in the same branch

I think what you propose here is a much better solution as the default behavior of --commit and would ask that you just make it do so. Creating a giant blob commit when it's multiple packages is harder to manage, and doing a branch but with a commit per package sounds way better.

@ehelms @Odilhao ping, it's been sitting a bit with no movement.

[Odilhao]

I've been using this since Pulpcore 3.21 branching, it worked as intended

[ehelms]

The thing missing for me here is that it removes the auto-creation of a branch for me which I have used a lot. I was hoping with this change you could keep that functionality but put it behind a parameter, e.g. --branch

Suggested change

	--branch When true, creates a git branch and commits the update changes to it.
	--branch When true, creates a git branch.

--commit does the second half?

[Odilhao]

No --commit only commits the package update, it does not create a new branch it can be used in a loop and it will only generate news commits and not new branches

[ehelms]

Ohh that's a bit confusing, I would expect:

• branch to create me a branch
• commit to create a commit
• branch + commit to create a new branch and commit

[Odilhao]

Yeah that's confusing, and I was confused. I'll refactor the code later today.
