MXS-2367 Print slave connection errors when replication fails
...
The slave connection I/O-tread stays running if replication credentials are
wrong when connecting to master. This causes a switchover/failover timeout.
When this happens, print the error in the slave connection status as this
clarifies the problem to the user.

MXS-2504 Kick out super-users from master server during switchover
...
The monitor queries for logged in users with super-privileges and kicks them out to
prevent writes to master. Normal users can stay since their writes are prevented by
read_only. Also, the master-status is removed from the master manually to signal to
routers that no more writes should go to master.

created at runtime could not, immediately after the creation, be
found using its name.
