Fix NFS issues with Nova

Fix NFS issues with Nova

There are problems with Nova launching instantces due to permissions
with nova being able to read/write certain directories on the NFS. The
permissions are right on the NFS and the folders the NFS mounts to, but
there still seems to be issues. The cause may be using a directory under
/root as the NFS mount. This patch moves the NFS mounts to be individual
folders under /. The patch also restart nova_compute docker container as
NFS problems still persist unless this is done.
