test: add test for worker that requires no instance profile

What was the problem/requirement? (What/Why)

The worker agent is able to be installed with the option disallow-instance-profile, in which case if the worker instance is booted with an instance profile, the worker agent will shut itself down and not run jobs.

We should verify that this functionality works as expected and that there are no regressions

What was the solution? (How)

Add a test to verify that the worker will not pick up any jobs in the case that the worker is configured to not have instance profiles, but the instance has a profile anyway.

Also upgraded test-fixtures version from 0.16 to 0.17 to allow for the option to disallow instance profile.

What is the impact of this change?

Better verification of worker agent installer code and behaviour.
