Replication to store filter in master.info

With multi source replication it would logical to have replication filters stored with other per domain replication informations. This would allow changing the replication topology using scripting without reconfiguring and restarting the server . Changing the filters on the fly is already a good step but if you lose the information after a restart it will break the replication. This will allow tools like MHA or SQL command like SWITCH MASTER to elect a a slave that get more schemas but contain at least all of the original master schemas and dynamically ignoring additional databases .
