Add linters for python, markdown (#177)

* Add linters for

- python
- markdown

Reason: Improve code quality

* Feat/linter with external flavors and formatting fixes (#186)

* Read mand flavors from SCS-Spec.MandatoryFlavors.yaml.

This implements #235.

* Be consistent about using f-strings

* Doc strings, f strings, line-length.

* Extra braces, one more f-string.

* flavor-name-check.py passing flake8 except E226, E501

* flake8 also for flave-names-openstack.py.

Also fix error introduced in Prop parser (when we exhaust the list).

* Use flake8 settings of my liking.

* Fix flake8 complaints (not enough blank lines)

* Fix flake8 complaints and *some* pylint suggestions.

* Use f-strings for formatting to please pylint.

Well, it also pleases my own eyes :-)

* Resolve merge errors.
