SOLR-16719: Let AffinityPlacementFactory have a spread_domain label (#1577)

Add the option in AffinityPlacementFactory to spread replicas across domains within each AZ. Optionally, the request can fail if more than a configurable number of replicas will be placed in a single spread domain

> Currently, {{AffinityPlacementFactory}} allows you to configure affinity based on "node type" and "replica type", as well as anti-affinity for AZs. I would like to add an optional anti-affinity label for nodes within the AZ. One use for this anti-affinity could be to make sure replicas for the same shard don't end up on the same {{host}} when a single host is running multiple Solr nodes (i.e. 8983, 8984, 8985...). It could also be used for rack-diversity within an AZ
