New DCA/DP flow including git-tfs

Hi Team, maybe it is useful for some other project that have to use Git and TFS together.

@matiasbeckerle, @gkolocsar, @gastonmancini. @jfazzini it is the updated flow to use Git in our projects, it is a simplified version of our previous flow.
I'm talking about the changes that occurr on `tfs/integration`. When is `tfs/default` updated with the changes that occurr in `tfs/integration` (version metadata changes, build dates, etc.)
