[2.1.5] apt http(s) proxy invalid url for custom TLD

[Felipe Reyes]

[Impact]

MAAS UI doesn't allow the use of custom TLD when setting the "APT & HTTP/HTTPS proxy server"

[Test Case]

* Go to Settings > Network Configuration
* Set the APT proxy to http://example.travel:3128/
* Save the configuration

Expected result:

* The apt proxy is set to http://example.travel:3128/

Actual result:

the save operation fails with the error "Enter a valid URL"

[Other Info]

The TLD '.maas' was whitelisted and it works. In my lab I have multiple vlans and each vlan holds a TLD (e.g.: some-host.vlan10) so I can only access my local proxy through the IP.

On the face of it MAAS really shouldn't have any business limiting which domains are in use.

[Andres Rodriguez (andreserl)]

I believe this issue is now resolved in MAAS 2.2+. (I've tested both 2.2.1 and 2.3.0 and have been unable to reproduce).
