Add vCPU topology related extra flavor keys

Since there is support to define default parameters for the vCPU
topology using flavor extra specs in nova now, it will be very nice
to add these extra flavor keys to local_settings.py.example

Re-enable flake8 check

This is the final fix to re-enable flake8/pep8 check in the gate.
E265 errors in doc/source/conf.py are also fixed.

Imports with "from xxxx import (xxxx)" style cannot pass "tox -e pep8"
though they pass "run_tests.sh -p". Newlines with backslash escape
is used in this commit to pass it.
The reason needs to be investigated later.
