import MAX config when running system tests

[zhindes]

• This contribution adheres to CONTRIBUTING.md.

What does this Pull Request accomplish?

Attempting to dynamically import the MAX configuration required for system tests rather than rely on the system image to have done that.

Why should this Pull Request be merged?

Less maintenance cost of the system image.

What testing has been done?

PR build ran the new test_ai_channel.py tests:

• Reported 50 more tests than before (1200 vs 1150)
• Downloaded the XML and confirmed those tests ran
• Log of import step looks correct
