chore: add initial pylint check

JohnVillalovos · JohnVillalovos · commit df93b2094f47 · 2021-12-05T17:04:28.000-08:00
Initial pylint check is added. A LONG list of disabled checks is also
added. In the future we should work through the list and resolve the
errors or disable them on a more granular level.
