Show License Information in WHM

As a WHM Administrator, I would like for the interface to have a page containing all the license information in the API with an automatic warning email warning of license expiration in order to simplify server administration.

============

Currently there is no information in WHM about the license currently assigned to your IP. I believe this information should be available within WHM and that you should be able to configure a threshold to warn you if you are near the limit.

Here are my suggestions:

- Show the current usage count on the main WHM screen, with changing colors when you are close to your limit.

- A separate page containing all the license information such as the type, expiration date, reseller, ...

- A button to refresh the license (same as running /usr/local/cpanel/cpkeyclt)

- Send a warning mail when you are near a threshold, if the license changes and if the license is about to expire.

- Make this information available via the API.

As licenses are often purchased via a datacenter or reseller and are assigned to IP, as a server administrator you have no control over it. At least provide us directly with information so we can react.

Feel free to add other suggestions!
