ctdb-recoverd: Change get_remote_nodemaps() to use connected nodes
The plan here is to use the nodemaps retrieved by get_remote_nodes()
in update_local_flags(). This will improve efficiency, since
get_remote_nodes() fetches flags from nodes in parallel. It also
means that get_remote_nodes() can be used exactly once early on in
main_loop() to retrieve remote nodemaps. Retrieving nodemaps multiple
times is unnecessary and racy - a single monitoring iteration should
not fetch flags multiple times and compare them.
This introduces a temporary behaviour change but it will be of no
consequence when the above changes are made.
