Disable it locally instead, so that
 1. new code additions are always checked, and
 2. we can refactor one function at a time to make the check pass.

The old printf-style string formatting syntax using '%' is not
recommended anymore. See for reference:
https://docs.python.org/3/library/stdtypes.html#printf-style-string-formatting
https://docs.sourcery.ai/Reference/Python/Default-Rules/replace-interpolation-with-fstring/

Python 3.6 introduced f-strings as a better alternative:
https://docs.python.org/3/reference/lexical_analysis.html#f-strings

Consequently switch to this new syntax for all strings.

Something we often do is check whether a list or sequence has elements
before we try and do something with it.

A Pythonic way of doing this is just to use the fact that Python lists
and sequences evaluate to True if they have elements, and False
otherwise.

Doing it this way is a convention, set out in Python's PEP8 style guide.

Adds scripts for mark down generation.
Adds scripts for lava test result queries.
Adds script to generate a mark down report from this data
Call script from submit_test to generate a report directly
after the testrun.

Fix pylint errors introduced with new pylint version:
* unspecified-encoding: explicitly set encoding when opening a file
* assigning-non-slot: use "set_reference()" function instead of assigning
  a value to the "reference" attribute
* unused-variable: remove "e" variable on exceptions when not referenced

Previously the default branch was allways used to generate the tests
from, now it is possible to specify the branch as cmdline option.
Additionally, the revision of the test repository is added to the
call of the test generator, so the tests run at a fix rev.

Uses submit_all instead of submit.
Some code cleanup also.

The testsuite is generated per platform and submited to the lava server.
The resulting jobs are monitored and the results are downloaded in the
results/ subfolder.
