ipaObject is defined as an auxiliary objectclass so it is up to the

ipaUniqueId is a MUST attribute so if you include the objectclass you must
ensure that the uuid is generated.
This also fixes up some unrelated unit test failures.
If we use cn for hostname there is no easy way to distinguish between
a host and a hostgroup. So adding a fqdn attribute to be used to store
the hostname instead.
Tied the make-test script into the test target of the top-level Makefile
Added code to xmlrpc_test.py so that it configures the API if it isn't
already done which enables individual tests to be executed.
