Wait for the region servers to report in. We will wait until one of this condition is met: -
the master is stopped - the 'hbase.master.wait.on.regionservers.maxtostart' number of region
servers is reached - the 'hbase.master.wait.on.regionservers.mintostart' is reached AND there
have been no new region server in for 'hbase.master.wait.on.regionservers.interval' time AND
the 'hbase.master.wait.on.regionservers.timeout' is reached
