PRCD-1334 PRCR-1065 CRS-2974 when stopping mgmtdb

Try to stop mgmtdb, and relocate mgmtdb to another node with below errors:

$ srvctl status mgmtdb
Database is enabled
Instance -MGMTDB is running on node racnode1

$ srvctl stop mgmtdb
PRCD-1334 : failed to stop database _mgmtdb
PRCR-1065 : Failed to stop resource ora.mgmtdb
CRS-2974: unable to act on resource 'ora.mgmtdb' on server 'racnode1' 
because that would require stopping or relocating resource 'ora.chad' 
but the -force option was not specified

Just relocate mgmtdb, it works.

$ srvctl relocate mgmtdb -node racnode2


$ srvctl status mgmtdb
Database is enabled
Instance -MGMTDB is running on node racnode2
