Checks done:
1. check if the topology is not disconnected. In other words if
there are replication paths between all servers.
2. check if servers don't have more than a recommended number of
replication agreements(4)

Mod of segment end will be disallowed in topology plugin.
Reasoning (by Ludwig): if we want to properly allow mods to change
connectivity and endpoints, then we would need to check if the mod
disconnects the topology, delete existing agreements, check if the new
would be a duplicate and create new agmts. There could be some difficult
scenarios, like having
A <--> B <--> C <--> D,
if you modify the segment B-C to A-D topology breaks and is then
reconnected.
