TrackFailedAllocationNodesTests needs local master node (#89975)

It doesn't make sense to reroute on a node other than the elected
master, so this commit sets up the cluster state appropriately.

It also runs the test with a replica which makes no difference to the
`BalancedShardsAllocator` but fixes compatibility with the desired
balance feature branch.
