Remove the web console EPP endpoint

This removes the "create Domain/Host/Contact" forms that were supposed to be used instead of regular EPPs for CC-TLD that wanted to support it.

We're removing it because we don't use it and want to reduce unneeded code for the registry 3.0 migration.

Also, this is a security risk, as it allowed to do "billable actions" (creating a new domain for example) with the only authentication being access to the registrar's G Suite account.

This bypassed the certificate, IP whitelist, and EPP password, which is bad.
