Use ConfigOpts.find_file() to locate policy.json

the standard default config paths.

Avoid unnecessary inst lookup in vmops _shutdown.

Updates the XenServer vmops.py _shutdown function so that it
avoids calling get_info/_get_vm_opaque_ref with the instance name.
Since _shutdown already has the vm_ref there is no need to make
this call.

This fixes an issue where 'RESIZE' was broken when resizing to
the same host.

Fixes LP Bug #997313.

API does need new image_ref on rebuild immediately.

This restores the DB update for image_ref immediately on rebuild, but
passes the old image_ref to the manager for use with instance.exists
notification.

Fix XenServer windows agent issue

Windows agent requires an argument of either 'agent' or 'xentools' to
the 'version' command.  All we care about is 'agent', so add it.  The
unix agent happily ignores the arg.
