apt::force: Added 2 parameters for automatic configuration file handling; fixes #modules-1306

Browse source 
when updating or installing newer packages with apt::force and you have changed previous
configuration files aptitude or apt-get will prompt what to do. You can suppress that
by pre-define the action with cfg_files parameter (new, old or unchanged and its backward
compatible if not defined). With a second optional parameter cfg_missing you can force
your provider to install missing configuration files as well.

apt::force: Changed selectors used in force.pp to case statements; refs #module-1306

Signed-off-by: Martin Seener <martin@seener.de>

apt::force: rspec: fixed the failing tests and added validate_re for cfg_files and validate_bool for cfg_missing. Also removed default values for both case statements and only allow pre-defined values or true/false. Furthermore enhanced the README refs #module-1306

Was able to fix the failing rspec tests for the patch.
Thanks to Morgan Haskel.

Despite the puppetlabs-stdlib documentation says validation_re supports 3 arguments the tests failed telling that only 2 are supported. Fixed this by removing the 3 optional argument; refs #modules-1306

### apt::force
Forces a package to be installed from a specific release. This class is particularly useful when using repositories, like Debian, that are unstable in Ubuntu.
The cfg_files parameter controls wether newer or older configuration files should be used or only unchanged configuration files should be updated. Cfg_missing forces the provider to install all missing configuration files. Both are optional.
apt::force { 'glusterfs-server':
release => 'unstable',
version => '3.0.3',
require => Apt::Source['debian_unstable'],
release => 'unstable',
version => '3.0.3',
cfg_files => 'unchanged',
cfg_missing => true,
require => Apt::Source['debian_unstable'],
}
You can additionally set the following attributes:
* `cfg_files`: "new", "old", "unchanged" or "none" (default). "new" will overwrite all existing configuration files with newer ones, "old" will force usage of all old files and "unchanged" only updates unchanged config files whereas setting "none" will don't do anything but providing backward-compatability with existing puppet manifests.
* `cfg_missing`: "true" or "false". Setting cfg_missing to false will provide backward compatability whereas setting true will add an aptitude/apt-get parameter which checks and installs missing configuration files for the selected package.
### apt_key
A native Puppet type and provider for managing GPG keys for APT is provided by this module.
