gitlab version support

[cdenneen]

Will there be Version support in the module?
Currently latest works but see few caveats:

1. if someone wants to lock to a particular version and not update
2. with a version parameter you can update on next puppet run, now you have to do a full "update" at the system level

It's already there, just set package_ensure to the version string of the package. F.e. to 8.0.3-ce.1 to install this particular version. Upgrading to a newer version is just as easy as bumping this version string. To see a list of available packages, have a look at f.e. https://packages.gitlab.com/gitlab/gitlab-ce
