The setUp/dearDown names are used in the unittest module, but there is no reason
to use them in non-`unittest` test cases.
Nose supports both styles (but mixing them can cause trouble when
calling super()'s methods).
Pytest only supports the new ones.

Nose doesn't pick up directories that don't begin with 'test'.
Rename ipatests/test_ipaserver/install to test_install so that it's run.
Also, merge test_ipautil.py from ipapython/test into tests/test_ipapython,
so the whole test suite is in one place.
