title: Is it possible to configure the remote registry endpoint heathcheck interval in harbor?
body: <p>After creating registry endpoints, I assume harbor checks periodically whether the remote endpoint is reachable. if not, the endpoint status is exposed as unhealthy.
  I would like to know if there is a configuration parameter to tune the period of this health check.</p>
  <p>Background information: it seems that if a remote endpoint is associated with a proxy cache project and in case of the remote endpoint is not yet detected as unhealthy, an image pull toward the proxycache harbor shall fail. harbor being unable to check whether the remote registry has been updated or not.
  After the endpoint is declared as unhealthy, harbor shall serve properly the image stored in the proxy cache.</p>
