Currently we are testing on beaker v3. There may be significant work upgrading our modules to run beaker 4. This may also include dependency bumps in modules and gems.

Example:
https://github.com/puppetlabs/beaker-rspec/blob/master/beaker-rspec.gemspec#L36
https://github.com/puppetlabs/puppetlabs-accounts/blob/master/.sync.yml#L22

We will need to come up with a plan on upgrading these.

Here is an upgrade guide: https://github.com/puppetlabs/beaker/blob/4.0.0/docs/how_to/upgrade_from_3_to_4.md

Dakota Schneider is prepared to work alongside our team to work on the upgrade and would appreciate us testing the following before merge: https://github.com/puppetlabs/beaker-rspec/pull/95/files
