novnc-by-default-from-package

[Ilya Kharin]

The change (https://review.openstack.org/#/c/54251/) that install the novnc from package by default was merged to the branch of master. After that I've got a problem to install the devstack from master because the novnc package requires the nova-common package by dependency. This package provides /etc/nova/api-paste.ini with nova:nova permissions on it. So, the process of nova-api that runned from not the nova user has got the "Permission denied" error. It's tested on Ubuntu 12.04 LTS.

The traceback from the window of the screen:
