v2.0.0-rc3

What's Changed

• Fix network cleanup issue by @jarlah in 7d5adf5
• Fix flaky kafka test by @jarlah in c00b3a5

Containers and networks are now properly cleaned up and tests pass 10 times in a row.

This is a huge breakthrough actually, since the tests have been very flaky from the start of the project.
