* branch-stx.sh is a first cut at creating milestone/release branches
in StarlingX repos. It includes branch creation and tagging the initial branch
point, and for Gerrit-based repos it creates a review to update the .gitreview
file to default to the new branch.
* getrepo.sh extracts repository names from given remotes to eliminate the
need to maintain that list separately.
