Fix pep8 issues, add 2.15 and 2.16 sanity ignore

[chynasan]

Description

Updated spacing and corrected ansible-test sanity pep8 line-too-long errors in plugins/modules/kafka_connectors.py.
Added tests/sanity/ignore-2.15.txt and tests/sanity/ignore-2.16.txt to ensure ignores are up-to-date for versions tested against. Added an ignore to .ansible-lint for the molecule directory.

Included 2.14 changes from #1557

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)

• This change requires a documentation update

How Has This Been Tested?

Ran ansible-test sanity --docker default in venv for 2.15 and 2.16 to confirm pep8 and other logging is clean.

thanks @chynasan for bringing this up. We analysed and ran into some more sanity failures for the ansible versions. The sanity check fixes are now added in the latest versions. Closing the PR, thanks for the contribution!
