Disable default Kubebuilder metrics (#397)
Disable default Kubebuilder metrics (#397)

Disable kubebuilder metrics by default as they don't
play well with the watch manager. Currently it's possible
for stale metrics to persist after restart. In addition, because
metric names correlate with template names, this means
that the installed constraint templates would be visible
if these metrics were enabled.

Default metrics can still be enabled by setting:

`--metrics-addr=":8080"`
