Add a receipt so auth_cmd exec only runs when parameters change.

Possible solution/workaround for #678

[rendhalver]

Can we get this merged please?

[johnzimm]

It looks like the "if receipt" logic has been implemented over in the puppetlabs "supported" repo: https://github.com/puppetlabs/puppetlabs-docker/blob/master/manifests/registry.pp#L69

I would assume that the puppetlabs repo now supersedes this one?

[rendhalver]

Weird. The puppetlabs version is one behind this one.

[rendhalver]

Oops silly me. The puppetlabs repo is 1.1.0 and this one is 5.3.0
This one has not been updated since 2016 so it seems likely the puppetlabs repo has taken over.

[johnzimm]

Yeah. I've made note to migrate my puppet-control. It seems the next issue opened here would be to just ask that a notice be posted in the README and Puppet Forge directing people to the puppetlabs module as it looks like the continuation of this code base and puppetlabs is tagged it as "supported" in the forge.

[rendhalver]

Sounds like a good plan.
