commit 9f2747e0bed3faca92679eae69aef10c95dc82f5
Author: Darren Tucker <dtucker at dtucker.net>

    Rework how selfhosted tests interact with runners.
    
    Previously there was one runner per test target (mostly VMs).  This had
    a few limitations:
     - multiple tests that ran on the same target (eg multiple build
       configs) were serialized on availability or that runner.
     - it needed manual balancing of VMs over host machines.
    
    To address this, make VMs that use ephemeral disks (ie most of them)
    all use a pool of runners with the "libvirt" label.  This requires that
    we distinguish between "host" and "target" for those.  Native runners
    and VMs with persistent disks (eg the constantly-updated snapshot ones)
    specify the same host and target.
    
    This should improve test throughput.
