refactored for Puppet 4 / Hiera 5

[crayfishx]

Summary

This is a refactor to modernize/refresh this module to work with Hiera 5 / Puppet 4.

Changes

• Removed params.pp pattern, replaced with Hiera 5 data-in-modules
• Removed hiera_hash() function calls, replaced with lookup_options in Hiera data
• Removed create_resources() function call, replaced with iterator
• Enhanced type validation on all parameters using native data types (note: hard/soft/both parameters are now required as integers, which matches the original documentation)
• Added more documentation around parameters
• Removed test coverage for Puppet 3 and added Puppet 5

It would be nice to get this merged - the module seems a bit dated as-is with use of deprecated features like hiera_hash....

Yes please! Lets leave the dark ages of create_resources behind.
