List test files dynamically (#313)
Motivation: Currently we have to manually update the all_tests variable
when introducing new test files.

Fix: I've modified it to list test files dynamically, but rather than
modify it to add all test files, I've first modified it to only add test
files from the following 4 paths so that it doesn't deviate too much
from what we already do

- unit
- unit/type
- unit/cluster
- integration
