gitlab-ctl repmgr-check-master exiting with wrong warning code
Currently exits 0 on the master, 2 on the primary, and 3 if something is wrong. This makes all non-master checks show up as critical in consul output.
We should update it to 1
for standby nodes, so they will show up as warning.
There is no real operational impact for the cluster do to this. It will make monitoring more complicated though.
