burn_in_test should run tasks on the distro they are normally run

When burn_in_tests runs the tests it discovered, it should run those tests on the distro they are normally run on. Otherwise, tests could fail due to resource constraints that are not normally there.

As a Server Engineer,
I want burn_in_tests to run on their normal distro,
so that I don't spend time investigating failure due to resource constraints.

AC:

• Tasks that normally run on non-default distros run on the same distros during burn_in_tests.
