Add new tool: oca-repo-add-branch

[simahawk]

Addresses 2 items of the usual flow to setup new Odoo version's branches:

• add new branch to all repos
• set it as default

Result for v18 OCA/repo-maintainer-conf#36

[simahawk]

I still have to address the use case to reuse answers from previous branch OCA/maintainer-tools#541

[simahawk]

To fix: preserve master branch defaults for tools' repo.

The files are ready on the conf. If we have to fix something we can do it manually there. This is just a manual tool to edit files.
