Setup a separate API Umbrella instance for testing multiproxy

[bajiat]

Deploy one API Umbrella instance on a web-accessible VM. This can be used for testing the multiproxy implementation.

• API Umbrella has been deployed on a new VM.
  Note: this is a standalone VM without any Apinf instance
• The VM has proper certificate, e.g. LetsEncrypt
• The server has a DNS record
