Ticket 49055 - Clean up test suites
    
    Description: Add all topology fixture imports
    for all suites and refactor them accordingly.
    Fix PEP8 and some logic issues.
    Set 2016 date in licenses.
    Fix create_test.py according to the new changes plus PEP8.
    
    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.
