[389-devel] Please review: Ticket 49055 - Add conftest.py for suites

Hi team,

please review the test suite improvement patch.

Description: Add all topology fixtures in conftest.py
for all suites and refactor them accordingly.
Fix PEP8 and some logic issues.
Set 2016 date in licenses.

For now we have:
- topology_st - with topology_st.standalone inst;
- topology_m2 and topology_m4 - with dicts
topology_mN.ms["masterX"]
topology_mN.ms["masterX_agmts"]["mX_mY"]

Using this setup we can easily run
through masters
and agreements in loops.
