Fix flake8 issues since release 3.6.0 Flake8 had a new release which raise new issues, namely: W504: line break after binary operator F841: local variable 'ex' is assigned to but never used W605: invalid escape sequence F821: undefined name 'buffer' (noqa seems the only way to avoid this false positive) Also pin flake8>=3.6 in our tests and make explicit that we use python3 to run flake8 tests.

RQL logs
========

You can configure the *CubicWeb* instance to keep a log
of the queries executed against your database. To do so,
edit the configuration file of your instance
``.../etc/cubicweb.d/myapp/all-in-one.conf`` and uncomment the
variable ``query-log-file``::

  # web instance query log file
  query-log-file=/tmp/rql-myapp.log
