Capella defaults num_replica to 1 while Couchbase Server defaults to 0.
Allowing num_replica to be undefined allows the user to use the default
for their environment.
Modifications
Allow num_replica to be undefined and don't send in the index create
or update query if it is undefined. Don't consider num_replica when
resizing existing indices if it is undefined.
Results
We are now more compatible with Capella behaviors. However, there is
still one remaining issue. Capella will ignore num_replica = 0 on
create and still create an index with one replica, causing the next
sync to resize to zero replicas. However, num_replica = undefined will
now behave consistently.
