[libvirt] [PATCH 2/2] snapshots: allow snapshot-edit to ignore validation

[Christian Ehrhardt]

This allows users to actively ignore validadtion if needed e.g. when
changing metadata intentionally that does not pass the ABI checker.

It is utilizing EDIT_RELAX of virsh-edit.c to set the
VIR_DOMAIN_SNAPSHOT_CREATE_NOCHECK flag defined in the former patch.
