Avoid multiple indexing operation for a single change

Before this code change, if active node calls passive node to index
some id and there already was an indexing operation for that id, we
ended up with multiple concurrent indexing operations. Adding tracking
of in-flight indexing operations allows avoiding multiple indexing
for the same id. Set of in-flight ids instead of locking fixes the
issue with occupying receivers threads while waiting for a lock.

Feature: Issue 13637
