Simon Willnauer 6522538033 Add validation for supported index version on node join, restore, upgrade & open index (#21830) ... Today we can easily join a cluster that holds an index we don't support since we currently allow rolling upgrades from 5.x to 6.x. Along the same lines we don't check if we can support an index based on the nodes in the cluster when we open, restore or metadata-upgrade and index. This commit adds additional safety that fails cluster state validation, open, restore and /or upgrade if there is an open index with an incompatible index version created in the cluster.
