  Collect clock_time_seconds metric from cert-manager
  cert-manager v1.5+ exposes a `clock_time` metric which reports the current seconds since the Unix Epoch
  See: https://github.com/jetstack/cert-manager/pull/4105
  
  It would be useful to collect this metric in DataDog so we can alert on seconds until a given certificate expires
