Ability for resellers to access MultiPHP UI
I've seen since the launch of MultiPHP feature, that resellers owning dozens of accounts will really find useful an UI within WHM to preset the PHP version to use in each and every account they own.
Obviously, the server main PHP version and the handlers list should be printed as a read only, informative text.
I'm not 100% sure if they should have the option to enable/disable PHP-FPM, because enabling it for lots of accounts could turn into a resource hog in some shared hosting scenarios. Maybe, the amount of accounts in which a reseller could enable PHP-FPM could be a preset value in the "Edit Reseller Nameservers and Privileges" UI for root users. Also, in that root UI the option to enable access to MultiPHP for resellers should have a checkbox to enable/disable on a reseller basis.
Even more, in despite that some servers will support PHP 5.4 and 5.5 for a long time, I, as a sysadmin, could have plans to abandon support for, let's say, PHP 5.4. So, the "Edit Reseller Nameservers and Privileges" UI should also allow to check what versions will we allow that reseller to implement. For instance, I could restrict resellers to use PHP 5.6 and 7.0 only. And this lead us to the MultiPHP UI for root users: if you as a sysadmin try to set a PHP version restricted for that reseller, the UI should prevent that action and show you a warning.
I hope this can be seriously taken into consideration because I believe it could be a time saver for both root admins and reseller users.
