ipaclient_test: More tests from ipaclient installer, updated ansible_ipa_client

The ipaclient_test module was not doing all tests that should be done
with the provided settings. All tests from ipaclient installer parts
are now part of ipaclient_test. There are some minor changes though to
make sure that the repair mode could still be used.

ansible_ipa_client bindings have been updated to fullfill new needs.
