features:
- HA services use a special container image name derived from the one
configured in Heat parameter plus a fixed tag part, i.e.
'<registry>/<namespace>/<servicename>:pcmklatest'. To implement rolling
update without service disruption, this 'pcmklatest' tag is adjusted
automatically during minor update every time a new image is pulled.
A new Heat parameter ClusterCommonTag can now control the prefix part
of the container image name. When set to true, the container name
for HA services will look like
'container-common-tag/<servicename>:pcmklatest'. This allows rolling
update of HA services even when the <namespace> changes in Heat.
