Hey all,

So I have a metric `fgHaStatsMasterSerial` which returns the following:
fgHaStatsMasterSerial{fgHaStatsHostname="HOSTNAME",fgHaStatsIndex="1",fgHaStatsMasterSerial="SERIAL2"} 1

The only thing I care about from that metric is the fgHaStatsMasterSerial label however is isn't very user friendly/pretty to view. So I'd like to perform a lookup against a different metric `fgHaStatsSerial` which returns a series for each device in the cluster. E.g.

fgHaStatsSerial{fgHaStatsHostname="HOST1",fgHaStatsIndex="1",fgHaStatsSerial="SERIAL1"} 1 fgHaStatsSerial{fgHaStatsHostname="HOST2",fgHaStatsIndex="2",fgHaStatsSerial="SERIAL2"} 1

I'd like to pull the fgHaStatsHostname variable from that metric and display it to the user. I'm essentially just trying to get the hostname of the current master in the cluster.
