push to git

[mcalmer]

Added scripts which push to git instead of OBS.

All based on the packages created with build-packages-for-obs

$> TEST=1 build-packages-for-obs
$> BRANCH=mybranch push-packages-to-git
$> BRANCH=mybranch push-images-to-git

and a script to mass create git repos

Usage: create-gitea-repos REPONAME [REPONAME...]

Create one or multiple git repos in gitea with the given names provided as
arguments.
You have to specify a "TOKEN" via environment variable to access the gitea API.

Optionally you can provide the following environment valiables:
GIT_ORG: The git organization (Default: Galaxy)
GIT_SRV: The git server (Default: src.suse.de)
GIT_BRANCH: The git default branch which should be initialized (Default: mlm-5.2)

apart from this, I just left a few minor comments.

@cbosdo : I added you as reviewer. not sure if you want to have a look at the changes. I think we are good in this way, but given that you reworked a lot the old scripts, I'm not sure if we are maybe missing something (or other places to fix)

[cbosdo]

Would it be worth moving the common functions to a helper script that would be sourced in both files?

[mcalmer]

Yes, when we have some time for re-org
