Yannick Welsch b503f05916 [Test] Fix rolling upgrade test to only wait for yellow in a mixed cluster
If the primary shard of an index with (number_of_replicas > 0) ends up on a new node in a mixed cluster, the replica cannot be allocated to the old node as
the new node might have written segments that use a new postings format or codec that is not available on the older node.
As x-pack automatically creates indices with number_of_replicas > 0, for example monitoring-data-*, the test can only wait for yellow in a mixed cluster.
