When we have many DUTs with the same tags (or subset of tags), it is
possible for the gitlab runner name not to match the DUT picked by
valve-infra's executor.
This is needlessly confusing, and prevents specifically tagging some
runners with a low-priority tag but still have these runners execute
high-priority jobs... because a low priority job may get started by
gitlab but the corresponding DUT is being used by a high-priority
task.
To fix this, simply tell the executor which DUT we want, not just the
list of tags we want.
