    Save admin password to sysmeta in libvirt driver
    
    We have an API for setting the admin password for an already created
    instance and we have a metadata API for retrieving the encrypted
    password. In the libvirt driver, when a request to set the admin
    password is received, it is indeed set in the guest but the instance
    system metadata is never updated with the encrypted password, so
    attempts to retrieve the password via the metadata service API result
    in an empty string returned instead of the encrypted password.
    
    This has been broken in the libvirt driver since the set admin password
    password feature was added, as far as I can tell. The xen api driver,
    however, handles the same thing correctly and this adds similar logic
    to the libvirt driver to fix the problem.
