Assign master status only to root level masters

Browse Source 
If a relay master server is found in the replication tree, it should not
get the master status. Previously all master servers were assigned the
master status regardless of their depth in the replication tree.

By comparing the depth value of each potential master, the monitor can
find the right master at the root of the replication tree.
