Upgrade core dependencies

Ugraded core dev dependencies (they needed to be regenerated). It's related to https://github.com/kytos-ng/kytos/pull/284.
Upgraded networkx to 2.8.6 to support py 3.9+ and minor fixes
I've also upgraded pylint and fixed linter errors that showed up.
For now, feature/upgrade_dependencies kytos branch is pinned just so tests pass in the CI. I'll revert this after before this PR gets merged after review.

Explored it locally still works as it used to:
