Support for RHEV with RHEL 6 nodes required us to output the old style qcow2 compat=0.10 images. Since RHEV 3.6 GA, RHEL 6 has not been supported as a RHEV node type. Since RHV 4.1, compat=1.1 is supported. (Support for compat=1.1 is uncertain in RHV 4.0 even on RHEL 7 nodes.)
There are significant downsides to using qcow2 compat=0.10 instead of the modern default (compat=1.1).
Therefore this patch does two things:
For -o rhev, it drops support for compat=0.10 completely. You must use RHV 4.1.
For -o vdsm, it adds an interim flag (--vdsm-compat=0.10 or --vdsm-compat=1.1) which controls the compat level of the qcow2 output file. VDSM should use --vdsm-compat=1.1 when it is known that modern qemu is available. We can make this the default later when all RHV instances have moved to 4.1.
It also adds:
vdsm-compat-option
to the `virt-v2v --machine-readable' output to indicate that this flag can be used.

LGTM, just one note below.
