Update our version of pylint to use the latest version and update the
codebase to comply with the majority of the updates.
For now disable the additional checks for `super-with-arguments`,
`useless-object-inheritance`, `raise-missing-from`, `no-else-raise`,
`no-else-break`, `no-else-continue` to be consistent with the existing
codebase.
Now allows for specifying a `group` value for each section which will
cross product the sections within that group with the sections in each
other group. Additionally classifiers will automatically be added to
each job spec with the relevant group information.
- Add copyright headers to files that did not already have them
- Update the year to the last year the file was modified in files with
existing headers.
Changing the way target descriptions work from a static mapping to
something that is dynamically generated and is extensible via plugins.
Also moving core target implementation stuff under "framework".
