Config & deployments to update overcloud packages

This change adds config and deployment resources to trigger package
updates on nodes. The deployments are triggered by doing a stack-update
and setting one of the parameters to a unique value.

The intent is that rolling update will be controlled by setting
breakpoints on all of the UpdateDeployment resources inside the
role resource groups.
