to increase readability, I'd personally prefer to have the imports ordered by:

1. import from the std lib. (e.g. errno, logging)
2. import 3rd party libraries (non in this case)
3. import ceph libraries (e.g. rados, ceph.deployment.service_spec)
4. import form the current package (e.g. orchestrator
5. relative import form the current package (e.g. .fs_util)

e.g.

import errno
import json
import logging

from ceph.deployment.service_spec import NFSServiceSpec, PlacementSpec
from rados import TimedOut

import orchestrator

from .fs_util import create_pool

jenkins retest this please
