Simple module to install Perl libraries via cpanm.

cpanm is a popular alternative to the CPAN client for installing Perl
libraries.  Unfortunately it can't uninstall already installed module, so it
can't handle states.
Add the `mirror` option and verify if a package is already installed.

By default, the cpanm client will use a default mirror to download
libraries, but it's possible for the end user to pass a different URL.

Since ansible favorite idempotence when possible, we verify if the
module is already installed before running the cpanm client.

Another minor additional change, the `notest` option is now a boolean.

made changes as per feedback:

- field names are more consistent with debconf
- values are now 'booleanized' or accepted as list/set objects when
  pertinent
- updated docs to reflect all of the above and debconf cli tools
  required
hopefully last batch of fixes

- removed previous 'typification' of input as it needs it is typed by
  module as strings and needs to be output as strings, making it
  useless.
- now checks for vtype and value against None when question is specified
- simplified set_selections as vtype and value should have a string
  value going in.
- added example of querying questions for a package
- added module requirement of question,vtype and value being required
  together.
Add support for checking host against global known host files.
