Currently, MetaDataUpgrader is only invoked during full cluster restart. Since 6.0 needs to support rolling upgrades we need to also invoke the same processes during rolling restart. This call should be performed when the last node with a version older than master leaves the cluster. A special meta data marker should be placed into cluster state to prevent old nodes from rejoining the cluster after the metadata is updated.

TemplateUpgraders should be called during rolling restart

In elastic#24379 we added ability to upgrade templates on full cluster startup. This PR invokes the same update procedure also when a new node first joins the cluster allowing to update templates on a full cluster restart.

Closes elastic#24680
