publisher_id of the versioned instance.update notification is not consistent with other notifications

[Balazs Gibizer]

Description
===========
The publisher_id of the versioned instance.update notification contains 'conductor' as the source of the notification but every other versioned notification use names like 'nova-compute', 'nova-api', 'nova-scheduler'. This makes the notification interface slightly inconsistent.

Steps to reproduce
==================
* boot a new instance
* check the publisher_id of instance.update notification

Expected result
===============
publisher_id contains 'nova-conductor'

Actual result
=============
publisher_id contains 'conductor'

Environment
===========
devstack with nova master dbf5fdb156f01196e8994798e8eea7e6b0926697
