Next Python SDK major

[sentrivana]

We're preparing our next major on this branch.

The project is tracked in Linear. If you don't have access, we'll try to tag issues belonging to the project with the SDK 3.0 label on GitHub so that you can follow along.

Notable changes

• Transaction-based tracing will be removed. Span streaming will be the default tracing model.
• Python 3.6 support will be removed.

Context

You might have read this announcement about us discontinuing work on a 3.0. This is referring to the work done on the potel-base branch, which included two types of changes: a huge refactor of our tracing code on the one hand, and various unrelated changes, improvements and fixes on the other. We're dropping the huge refactor part, and only porting the rest, to a new branch and eventually a new 3.0 release.
