Hide PFS fields based on "use git" choice AND hide import barclamps [1/2]

This small change hides fields for PFS unless the user is turning on that feature.
Since all the PFS barclamp features uses the same partial, this is a minor update that
will impact the UI on all the OpenStack PFS barclamps.

Also, moved the "barclamp import" screen under the dev mode flag because we 
are not testing it and should not expose it in the production UI.
