Get the replica count for the servers provided.
<p/>
For each server, replica count includes three counts for primary, secondary and tertiary. If a
server is the primary favored node for 10 regions, secondary for 5 and tertiary for 1, then the
list would be [10, 5, 1]. If the server is newly added to the cluster is not a favored node for
any region, the replica count would be [0, 0, 0].
