Automation - CiTests: Make debugging easier

Debugging the CiTests isn't very straightforward today. Once #1436 and #1437 are addressed, and it's easier to run/iterate on them, this will definitely be the next pain point.

A few possibilities we could have to make this easier:

• Add a npm run debug:test:integration command, that opens a debug window and stops at a debugger prior to executing the test.
• All the npm run debug:test:integration to take some sort of filter that is scoped to a particular test (so we don't have to run them all).
