Adjust requirements and lower-constraints

Conservative changes to get the l-c job passing with the new
pip resolver.

Big changes:
- os-win 3.0.0 -> 4.1.0 (u-c allows 5.2.0)
- oslo.service 1.24.0 -> 1.31.0 (u-c allows 2.4.0)
  * These were the minimum versions that can take eventlet >=0.25.1
    (which os-brick wants)
- pytz 2013.6 -> 2015.7 (u-c allows 2020.1)
  * needed for babel
- remove pycodestyle from test-requirements (let hacking request
  flake8 which will request the pycodestyle version it wants)
- requests 2.14.2 -> 2.19.0 (u-c allows 2.23.0)
  * oslo-config wants >=2.18, but 2.19.0 doesn't use idna (which
    was causing a conflict)
