feat(poly test diff): extract related bricks from changed tests

[DavidVujic]

Description

Adding the possibility to find related bricks for changed tests. The existing behaviour of the poly test diff command is to inspect the tests, and find bricks by the imports made in the tests.

This new feature adds a --strategy path option to find the corresponding brick according to the folder structure.

Example

A changed test in test/components/my_namespace/my_brick/the_test_for_the_brick.py,
the poly tool will look for a corresponding/related brick in components/my_namespace/my_brick.

fixes issue #459

Motivation and Context

The idea and implementation suggestions is from issue #459

How Has This Been Tested?

✅ CI
✅ added unit tests
✅ local run of the poly test diff command.
