Prefix- should not be removed from directory name

[russellshackleford]

pdk new module foo-module pre-fills the forge name in the questionnaire as well as writes it into metadata.json. Why should it not also keep the prefix in the directory name, too? It is also likely going to be the git repo name. I know some people don't name their repos that way, but then, they'd have to rename the created directory regardless, so changing this would make no difference to them.
puppetlabs-* and puppet-* are obviously a large number of the "supported" modules and thus repo name and metadata name are the same. Some people prefer to namespace their module as puppet-module to make it easier to find/navigate in github, but again, they would have to rename the directory regardless of this change. And then you have the oddballs, like sensu-puppet, which doesn't even align with the module name itself. Thoughts?
