A change was added to the import API which provides time-based
locking of an image to exclude other import operations from
starting until the lock-holding task completes (see Bug
1884596_). The lock is based on the task that we start to do the
work, and the UUID of that task is stored in the
``os_glance_import_task`` image property, which indicates who owns
the lock. If the task holding the lock fails to make progress for
60 minutes, another import operation will be allowed to steal the
lock and start another import operation.
