Add a way to set a default supervisor TLS cert for when SNI won't work

Browse Source 
- Setting a Secret in the supervisor's namespace with a special name
  will cause it to get picked up and served as the supervisor's TLS
  cert for any request which does not have a matching SNI cert.
- This is especially useful for when there is no DNS record for an
  issuer and the user will be accessing it via IP address. This
  is not how we would expect it to be used in production, but it
  might be useful for other cases.
- Includes a new integration test
- Also suppress all of the warnings about ignoring the error returned by
  Close() in lines like `defer x.Close()` to make GoLand happier
