[libvirt] [PATCH v3] virsh-edit: Make force editing usable

When editing a domain with 'virsh edit' and failing validation, the
usual message pops up:
Failed. Try again? [y,n,f,?]:
Turning off validation can be useful, mainly for testing (but other
purposes too), so this patch adds support for relaxing definition in
virsh-edit and makes 'virsh edit <domain>' more usable.

v3:
- turn 'v' into an 'i' (as in "Ignore validation")
- fix translation
v2:
- make a special case 'v' for turning off validation
