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.
It is explained at `6` (there are console commands below):
> And all QA and Intergration changes should be backward merged to Develop

I also mentioned merges to `develop` at `5`
> Changes on `integration` and `qa` are fairly often merged to `develop`.
