Adopt use of pre-commit hooks

- rename pep8 target to more generic linters
- migrates flake8 execution to pre-commit
- adds yaml linting
- hardening flake8 rules
- setting max-line-lengh to 120 instead of ignoring it.
- bumped minimal sphinx version
- configured sphinx with warnings as errors

 Writing a patch
 ---------------
 
-We ask that all code submissions be flake8_ clean.  The
-easiest way to do that is to run tox_ before submitting code for
-review in Gerrit.  It will run ``flake8`` in the same
-manner as the automated test suite that will run on proposed
-patchsets.
+Be sure that you lint code before created an code review.
+The easiest way to do this is to install git pre-commit_ hooks.
