Remove dependency between ipa-pyton and ipa-server

Current ipa-python imports and calls code from ipaserver (which is in
the ipa-server package). This makes it impossible to use the admin
tools or the ipa-python package on a system without the server bits
installed. This fixes that in a fairly minimal way.
