When a BITS job is being transferred, it may enter into the state
BG_JOB_STATE_TRANSIENT_ERROR (for example, if the hostname fails to
resolve). Currently, entering this state causes qmgr job tests to fail,
even though it may occur due to temporary network issues out of our
control.
If a job enters BG_JOB_STATE_TRANSIENT_ERROR before the timeout has
elapsed, attempt to resume the job using
IBackgroundCopyJob_Resume. If the job is still in
BG_JOB_STATE_TRANSIENT_ERROR, query BITS for detailed error
information, and print it out.
Additionally, ensure that we are able to transfer files on Windows 10
with a metered connection. By default, BITS will not attempt to transfer
a job on a metered connection, instead failing with
BG_JOB_STATE_TRANSIENT_ERROR. On newer versions of Windows, we can
use IBackgroundCopyJob5 to set the transfer policy, forcing the job to
run even on a metered connection. This allows qmgr job tests to pass on
the testbot Windows 10 VMs, which have metered connections enabled in
order to disable Windows Update.
