doc: git-dpm to gbp

(Sorry, I found no way to send merge request compared against previous merge request)

I think we need discussion about this. For example in OpenStack team we removed d/gbp.conf file completely.

please remove it for now, thanks.

If we keep the debian/master branch naming convention we need a gbp.conf file. You also need it as soon as you're making a backport on a branch that's anything else than master.

Finally, if your package uses pristine-tar, you really should have that set in gbp.conf or you'll get some fun results with the default gbp-buildpackage settings recreating the tarball from a git archive, and getting yelled at by the archive for having a different orig tarball. This is all the more so annoying for "drive-by" uploads by team members. I think mandating the use of pristine-tar is a sensible default.
