Attempting to fix NFS issues

Issues still persist where sometimes instances fail to start due to a
failure with os.utime to read the file path. This could be some bad race
condition between qemu/nova while copying images on the NFS. This patch
adds more ports to open in firewall, and changes initial directory owner
to nfsnobody.

Also, includes a patch to fix an apparent race condition when nova sends
a remote call to the privsep helper daemon to modify the time of the
base file owned by qemu:
https://review.openstack.org/#/c/625741/

Includes another fix for patching container images where the docker
image was not being detected correctly because the full gerrit project
name including 'openstack/' prefix was being used to search tripleo
docker images. Additionally, there were more bugs around patching
openstack python containers where the patch was not being applied
correctly.
