[libvirt] [PATCH 2/5] virsh: Implement "domrename" command
This patch implements new virsh command, domrename.
Using domrename, it will be possible to rename domain from the virsh shell by
calling virRenameDomain API.
It takes two arguments, current domain name and new domain name.
Example:
virsh # list --all
Id Name State
----------------------------------------------------
- bar shut off
virsh # domrename bar foo
Domain successfully renamed
virsh # list --all
Id Name State
----------------------------------------------------
- foo shut off
virsh #
