Update for Puppet 7 compability

[tkishel]

Puppet 7 removes lib/puppet/ssl/host.rb and the Puppet::SSL::Host class.
The Puppet.valid_digest_algorithms method works just fine.
This addresses Issue #85

Hi friend!

Hello Friend!

This was in response to a post in the puppet Slack channel.
It should close Issue 85 (once someone builds and uploads this module to the Forge!)

Hi Puppet :)
What's the point of a stale bot that closes PRs where the community waits for reviews from your side ;) Any Chance this can be merged in the near future?

Hey @bastelfreak,

With community day starting again soon, I'm hoping we will get less of these instances.

I've removed the label so this PR is active again.

LGTM

Was a little worried about the support changes being in the same PR, but can work around that for the release
