2016-03-09Upgrades: initialization command/snippetJiri Stransky1-0/+11
This allows to run a command or a script snippet on all overcloud nodes at the beginning of the upgrade. The intended use is to switch to a new set of repositories on the overcloud. This is done differently in different contexts (e.g. upstream vs. downstream), but generally it should be simple enough to not warrant creation of switchable "UpgradeInit" resource in the resource registry, and a string command/snippet parameter should suffice.
