https: T5902: remove virtual-host configuration

We have not seen the adoption of the https virtual-host CLI option.

What it did?
* Create multiple webservers each listening on a different IP/port
  (but in the same VRF)
* All webservers shared one common document root
* All webservers shared the same SSL certificates
* All webservers could have had individual allow-client configurations
* API could be enabled for a particular virtual-host but was always enabled on
  the default host

This configuration tried to provide a full webserver via the CLI but VyOS is a
router and the Webserver is there for an API or to serve files for a local-ui.

Changes

Remove support for virtual-hosts as it's an incomplete and thus mostly useless
"thing". Migrate all allow-client statements to one top-level allow statement.
