Change in super-linter fail-under from 9.0 to 10.

[ArekKuczynski]

After fixing enough errors related to the coding standards we should set fail-under back to the 10 in .python-lint file. Some Pylint codes requires changes to the code, and others perhaps adjustments to the configuration file (.python-lint) like: R1702-[too-many-nested-blocks], R0912-[too-many-branches], R0915-[too-many-statements], R0904-[too-many-public-methods], R0902-[too-many-instance-attributes], R0903-[too-few-public-methods], etc.

Some codes appear in small numbers (3 for example) and the larger ones have been mentioned in issues: #275, #276, #277, #278, #279, #280, #281, #282, #283, #284
