**Support ACL based on Domain/URL instead of IP**

- As a company, sometimes i would like to block access to specific sites (eg. google drive), which is based on domain.
- But i am unable to do so because, ACL Rules are based on explicitly specifying the IP address.
- Specifying the IP address/range of the intended website will be tedious and non-practical.

Start by reading the linked original issue 8841 and the existing ACL functionality in CloudStack. Define how domain/URL-based rules should be configured and enforced, then confirm the behavior supports blocking sites such as Google Drive and is covered by appropriate tests.
