[7.0] 'module_repository'  new. Informations of Modules Repositories

Hi all,

I propose this modules to see faster wich repositories are used on a Odoo Database (url, name, revision), if there is local (ie = unstaged / uncommited) modifications, etc.
See screenshots to see covered features.

Thanks for your review.

*Remarks:*
Flake8 : OK;
Coverage: ~75 - 90 % (depending of your version controls during the tests)

To get informations about source version, I used 'git' and 'bzrlib' librairies. I'm not very confortable with that libraries. If some reviewers know better that librairies please propose improved code.
