Description of problem:
The only way to configure Puppet agent during host registration is to use the host parameters puppet_server, puppet_ca_server and puppet_environment. While the Puppet servers appear in puppet.conf after the registration, the Puppet environment configuration key and value are missing.

Version-Release number of selected component (if applicable): N/A

How reproducible: always

Steps to Reproduce:
1. Set global host parameters: enable-puppet7, puppet_server, puppet_ca_server, and puppet_environment
2. Register the host with Puppet agent provided in an activation key.
3. Check puppet.conf on the host.

Actual results:

puppet.conf contains "server" and "ca_server" config values, but not the "environment" key and value.

Expected results:

puppet.conf should contain also "environment" with the value defined in the "puppet_environment" host parameter.
