enhancement: Global Scopes Support

[robsoncombr]

Hello,

In my system, I have 'environment' and I use Global Scopes, so sudo-su does not return all available users in the database.

We could be able to choose if we want to ignore Global Scopes in config file so on SudoSu.php > getUsers() method, based on configuration, you could run $user->withoutGlobalScopes()->get() instead of only $user->get()

Hope it is a nice idea and is implemented.

Thank you,

Robson
