C3: E2E logging refactor

[jculvey]

What this PR solves / how to test:

This is a long overdue rework of how we handle logging in c3 e2e tests.

The current e2e logging situation is extremely annoying. The test runner pipes output directly to stdout with minimal filtering, and since the output contains interactive cli commands it's usually cluttered with various animations and terminal escape codes. To make matters worse, tests are run in parallel and output to the same stdout, which means that the output of multiple frameworks are interleaved with one another, making almost impossible to discern where the output of the problematic test begins and ends.

This PR changes things by:

• Formatting the output in a simpler way for non-interactive terminals (which happens to be useful outside of testing as well)
• Giving each test its own dedicated output log. Each file gets it's own folder, and each test attempt gets its own file. If a test is retried, each attempt gets its own file
• Fixes an issue where the cleanup script was being run as a side effect of import, often running the cleanup script more often than was required
