Felix Bünemann 4ecb17cc4c registry: support whitelisting letsencrypt hosts 
This adds a configuration setting `HTTP.TLS.LetsEncrypt.Hosts` which can
be set to a list of hosts that the registry will whitelist for retrieving
certificates from Let's Encrypt. HTTPS connections with SNI hostnames
that are not whitelisted will be closed with an "unknown host" error.
It is required to avoid lots of unsuccessful registrations attempts that
are triggered by malicious clients connecting with bogus SNI hostnames.

NOTE: Due to a bug in the deprecated vendored rsc.io/letsencrypt library
clearing the host list requires deleting or editing of the cachefile to
reset the hosts list to null.
