maas api "device update <id>" requires setting parent= in addition to hostname=, but it's not documented as required

[Dimiter Naydenov]

Using the same scenario described in bug 1440994, I've tried running:

$ maas maas-user device update node-a13335fa-dcf1-11e4-82db-525400355a63 hostname=juju-machine-0-lxc-0-newhost

But despite the documentation of the "update" method only mentioning "hostname=" as accepted argument it appears "parent=" is also required. Response I got:

{"parent": ["Select a valid choice. That choice is not one of the available choices."]}

Trying again with parent=foo reports the same error (as expected). Trying with "parent=<system-id-of-another-ready-node>" works: http://paste.ubuntu.com/10758933/

It will help to document "parent=" as accepted argument to "device update", but also make it optional.

Confirmed.

Devices that have no parent work as expected, but devices that previously had a parent exhibit this behavior.

Confirmed as fixed in 1.8.0~beta2+bzr3814-0ubuntu1~trusty1 - parent is no longer required.
