Ability to satisfy hostname in url

[SJang1]

I think ability to satisfy hostname to check if server status, will make more great on checking the server.
on Browsers, it sends as Host on the header
and on curl can use like this : curl -H "Host: www.google.com" http://172.217.164.100/

After making it, maybe could be used like this (Main useage why I think it's needed) :

  - name: Google with IP address
    url: http://172.217.164.100/
    host: www.google.com

or also like this :

  - name: Google just with hostname
    url: http://www.google.com/
    host: www.google.com

You can add a custom header since the Host is just a regular request header: https://upptime.js.org/docs/configuration/#request-headers

- name: Google with hostname
  url: https://www.google.com
  headers:
    - "Host: www.google.com"
