  - Apex: Fixes scheduling with apex verify

    apex-verify job calls apex-virtual to deploy and run functest.  Apex has
    2 virtual slaves attached to the apex-virtual-master label.  When 2
    verify jobs are triggered at the same time, apex-verify job is scheduled
    on each slave correctly.  However, when the mulitjob triggers
    apex-virtual jobs, it only schedules both of them to a single slave.

    This happens even though apex-virtual job has the same slave label and
    node parameters are not passed from verify job.  This patch changes the
    node to be passed to apex-virtual from apex-verify.  That way 2 nodes
    will be scheduled on, but this is still not ideal scheduling as more
    than 1 verify can run per node (but not more than one virtual job).
