Only show Gerrit instances in the instance dropdowns

A variable was used to select the Gerrit instance to observe in the
dashboards. Since the instance label is set for all targets that
prometheus scrapes, the variable would also contain e.g. the prometheus
instance.

Now only Gerrit instances are displayed by further filtering for a
metric specific for Gerrit.
