Replace the module ios_user with a more standard file coverage.
And also take correctly some parts of the commands (by example, the
current module doesn't take correctly the `privilege`part of the
username command

Currently, on IOS devices, when you enter a `no username` command, the
system request you a question to confirm the suppression.

To handle this part, I have done some change:
- I have "created" the module IosNetworkTemplate, a override class of
  NetworkTemplate that take care the case of commands with a specific
  prompt
- The ios_user_global module use this class for the User_globalTemplate

Second point, this module allow you to create the username by using the
old command line (C(username)) or the new one (C(user-name)).

I have done this part in a super class to allow other template module to
use this possibility.

I don't have done a super class for the assert function in tests module.
If you want, I can try to do it also.
