[test_all] Rewrite in Python (#4769)

Rewrite test_all in python.
Bash is quite annoying to write and test.
One issue with bash is it is even worse than Python for parallelism (which may be causing #4707).
Rewrite test_all in python and optimize base-runner/Dockerfile for fast development.
Also, combine some docker layers.
