chown commands failing (no rootwrap filter)

[Eric Berglund]

Description
============
https://review.openstack.org/#/c/471972/31/etc/nova/rootwrap.d/compute.filters

The above changed removed the chown rootwrap filter. However the temporary_chown method in nova.utils is still calling execute('chown',...) which is failing. This needs to be converted to use the new nova.privsep.dac_admin chown method.

Environment
===========
Openstack version: master

[Michael Still (mikal)]

This affects xen in tree, and at least powervm out of tree. https://review.openstack.org/#/c/503079/ is the fix.

    Fix missed chown call

    When privsep'ing chown calls, this one was missed. Fix that.

    I think this entire method should go away, but it will break at least
    one of out tree driver. I'm talking to the powervm guys about a way
    forward there.
