[SRU] python-pysnmp4 pkg inconsistent in cosmic

[Corey Bryant]

[Impact]
I hit the following error when running ceilometer unit tests for cosmic:

=========================
Failures during discovery
=========================
--- import errors ---
Failed to import test module: ceilometer.tests.unit.hardware.inspector.test_snmp
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/unittest2/loader.py", line 456, in _find_test_path
    module = self._get_module_from_name(name)
  File "/usr/lib/python2.7/dist-packages/unittest2/loader.py", line 395, in _get_module_from_name
    __import__(name)
  File "ceilometer/tests/unit/hardware/inspector/test_snmp.py", line 23, in <module>
    from ceilometer.hardware.inspector import snmp
  File "ceilometer/hardware/inspector/snmp.py", line 21, in <module>
    from pysnmp.entity.rfc3413.oneliner import cmdgen
ImportError: No module named oneliner

It turns out the tarball that is pulled from git to build pysnmp4 is missing files, such as pysnmp.entity.rfc3413.oneliner. The release artifact from pypi.debian.net is not missing the oneliner directory.

[Test Case]
Building the ceilometer package for rocky should be successful with a good version of pysnmp. I also plan to run tempest regression tests on a full openstack deployment to help ensure there are no regressions.

[Regression Potential]
The current state of pysnmp4 at 4.4.6-1 is incomplete, therefore the diff from 4.4.6-1 to 4.4.6+repack1-1 is not minimal. Most of the diff, however, is added files/directories that were missing in 4.4.6-1. Note that 4.4.6+repack1-1 is already in Debian unstable and the fix for this bug is to sync from unstable. This version has been in unstable for 2 months which should have provided some regression coverage.

This bug was already fixed in Debian, however this was fixed after cosmic was released via a +repack in sid:

debian:
 python-pysnmp4 | 4.4.6+repack1-1 | unstable | source, all
ubuntu:
 python-pysnmp4 | 4.4.6-1 | cosmic | source, all
 python-pysnmp4 | 4.4.6+repack1-1 | disco | source
 python-pysnmp4 | 4.4.6+repack1-1 | disco/universe | all

This was fixed via the following bug:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=910269

Can we sync from unstable to cosmic at this point to fix this?
