pytest: Migrate xunit-style setups to Pytest fixtures

Even though Pytest supports xunit style setups, unittest and nose
tests, this support is limited and may be dropped in the future
releases. Worst of all is that the mixing of various test
frameworks results in weird conflicts and of course, is not widely
tested.

This is a part of work to remove the mixing of test idioms in the
IPA's test suite:
1) replace xunit style
2) employ the fixtures' interdependencies
