If you attempt to update a stack containing
OS::Heat::SoftwareDeployments resources, so it uses the new
non-deprecated OS::Heat::SoftwareDeploymentGroup type instead, it
deletes the group, and all of the deployments.
This means that any deployment "actions" property will be
misinterpreted, e.g if you have actions: CREATE, all the deployments
will re-run on the update, even though it's an update, not a create.
This issue exists on all deprecated resoruces, when we trying to upgrade
to new version of it by update.
This patch fix above update issue by check if resoruce was deprecated
and been update by replacing resource (which is the parent class of
existing resource).
