contrib: add a new script to update remote repos
This script allows us to split ceph-ansible role directory into repositories that can be pushed. This script is an enhanced version of splitup.yml that was using git subtree. I haven't found any straighforward way to push tag using git subtree where git filter-branch seems easier and more practical. Now we can not only push commits from master but also all the relative tags. It is nice for projects that want to consume our roles from the Ansible Galaxy, pointing to a specific tags looking for a particular release. For backward compatobility, I pushed a branch called "master-history-bkp" on all the github.com/ceph/ansbible-ceph-* repositories. So current projects using a SHA to retrieve the roles won't be impacted by this change. At the time of the commit, running this script took 104.60s to complete.
