VMU: Add duplicate test runs

Description

Add support for running copies of a test (VM image × repo set × package set) in a single VMU run. This lets us spot random failures.

Currently we spot random failures by comparing CentOS 7 and SL 7 test runs – differences between otherwise identical tests were almost always spurious. There is no SL 8 so the only thing we can do is run CentOS 8 twice.
