Give the module a Modulefile
Consolidate install and service, use module-data

Get rid of the decomposed install and service classes and put the package and
service resources directly into the main class. Also, get rid of the params
class in favor of module-data.
Various fixes

- Fix up the formatting
- Get rid of easy-rsa based key handling and just source the files instead,
this delegates the actual creation and distribution of key/cert files to the
module user.
- Parameterize the crypto configuration
Release 0.1.0
Ignore the pkg directory
