I'm not a big fan of having both `$server_dynamic_environments` and `$server_dyn_envs` as there is not the clear the difference between those two and might lead to confusion. The only place it would help us is https://github.com/theforeman/puppet-puppet/pull/100/files#diff-fcc94db824af4a315844f3f1970eda8eR19 and I'm not sure it's worth it.
