Always specify qcow2 compat level on qemu-img command line

Browse Source 
qemu-img is going to switch the default for QCOW2
to QCOW2v3 (compat=1.1)

Extend the probing for qemu-img command line options to check
if -o compat is supported. If the volume definition specifies
the qcow2 format but no compat level and -o compat is supported,
specify -o compat=0.10 to create a QCOW2v2 image.
