Any job which touches migration parameters will first store their
original values (i.e., QEMU defaults) to qemuDomainJobObj to make it
easier to reset them back once the job finishes.

The qemu command line generator code set disk caching of shareable disks
to 'none' when formatting the command line silently. Move this code to a
common place when preparing the domain definition for startup so that it
does not have to be duplicated.

The new test case shows that the actual cache mode will now be recorded

When trying to destroy a domain (e.g. because we've seen EOF on
the monitor) we try to acquire QEMU_JOB_DESTROY. However, if
max_queued is set in qemu.conf this may fail and since our code
doesn't count on that we will still report domain as active even
though the qemu process is long gone. More specifically, if we've
seen EOF on the monitor, qemuProcessHandleMonitorEOF() is called
which sends MONITOR_EOF job to the event worker pool and
unregisters monitor from the event loop. The worker pool calls
processMonitorEOFEvent() which tries to set job which may fail
due to the limit as described above.
