Huntgroup

[amateo]

There was duplicate functionality for huntgroups since #93. Since that PR, freeradius::module::preprocess and freeradius::module::huntgroup wasn't working.
This PR deprecates freeradius::module::preprocess (while still works).

Can you briefly explain these changes, please? I don't use huntgroups and I didn't write this original code 😄

I made a PR #59 in Feb'17. That PR added freeradius::module::preprocess to configure preprocess module (basically, to enable the module and initialize an empty huntgroup file), and freeradius::module::huntgroup was added too to create huntgroups entries.

Later, PR #93 did the same in a different way. In that PR the empty huntgroup file was created directly in init.pp file and freeradius::huntgroup is added to add huntgroups entries.

The problem is that this later PR conflicts with the former.

What I have done in this new PR is:

• Changed freeradius::module::preprocess so that it just enables preprocess module (and doesn't create the empty huntgroup file)
• Changed freeradius::module::huntgroup to call freeradius::huntgroup and display a deprecation warning message.

This way, anyone can continue using huntgroups in the same that #59 or in the #93 way, without any problem.

OK, sounds good. Thanks!
