Bumped version to 1.1.1

Deleted deprecated Modulefile, and replaced it with a proper metadata.json file.
Fixed a misfiring resource

The conditional statement used to judge whether or not the foreman_repo
hash attribute had a 'tag' key in it was wrong. Changed it to use a function
provided by the stdlib module.
Updated README.md
Merge branch 'hotfix-1.1.1'

- Fixed a conditional issue that was causing a resource to fire unexpectedly
