I do not duplicate here the component description, it is quite comprehensive in the commit message and comments. The only noticable thing is that the component alone does not care about changed uuid steady dissemination. Here UUID update looks just like any other update with some minor differencies. And it leads to a 'bug', that even with the stable network and the fullmesh a ghost of the old UUID will live in the cluster until it is dropped by failure detection component. It takes long time, since ack_timeout is 30 seconds by default, and it is necessary to unack 5 pings to drop a member - 2.5 minutes in total. Next patches will fix that problem for the most popular case.
