Pylint Fixes

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.
