CoreDump using maxadmin

What the replication manager do is in monitoring go routine pool the servers lists and the monitoring list

During switchover we do

• set master flag and remove slave flag to the elected master
• set slave flag and remove master flag to the old master

After a signifiant number or retried we are able to crash the maxscale.

Nota that i do open and close the connection in failover and monitoring code
