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.
- 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.
Upon initilisation WA3 will now also check if a WA3 config file
exisits, rather than just the exsistance of the config directory.
If a `config.yaml` file is not found WA will look for a WA2 config.py
file and convert it to the new format, otherwise a default config file
will be generated.
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".
