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.
Is this a typo or is there a function called `ffetch` with double-f?
