chore: @rest endpoints are now run by starlette/uvicorn instead of flask/werkzeug

[viniarck]

Closes #123
Closes #124

This PR depends on kytos-ng/kytos#375

(I'll revert the pinned branch feat/starlette on requirements/dev.in later on, it's need for tests to pass)

Summary

See updated changelog file.

Notice that requirements/dev.in is being used directly now instead of requirements/dev.txt to simplify code maintenance and house keeping, for more information check out the linked issue, in summary, we're making a trade-off to trust kytos-ng dev upstream transitive dependencies.

Local Tests

• Exercised with a ring topology a few endpoints
