Commits on Jan 7, 2021

  1. kvserver: refactor testing utilities dealing with range splits 

    This commit extracts some existing testing methods to be more general.
so they can be reused for testing merge queue behavior with non-voting
replicas.

  2. kvserver, roachpb: rename ReplicaDescriptors to ReplicaSet 

    This commit renames `ReplicaDescriptors`, which provides some utility
methods over a `[]ReplicaDescriptor`. This is because the current naming
makes it hard/confusing to add new methods that return another
`ReplicaDescriptors` instead of the underlying slice.

Release note: None

  3. kvserver: make AdminRelocateRange work with non-voting replicas 

    This commit teaches `RelocateRange` to work with non-voters. This lets
the merge queue rebalance a range that has non-voters so the merge can
actually proceed, as range merges require that replica sets of the LHS
and RHS ranges must be aligned.
