From: Suresh Babu Angadi <sureshab at in.ibm.com>
In case of s390x architecture, console type can be
either virtio/sclp. Extended current code to support
console configuration in case of s390x
* added 'console' parameter as optional attribute for s390x
which returns current console type attached to guest
* made changes in model code to support update of 'console'
attribute for guest when running on s390x
* added appropriate error codes in i18n.py
* added API.json changes to validate 'console' attribute
* made changes in xml code generation, default value as
'virtio'
