[Bug 1700677] Re: nova-api conflicts with nova-placement-api in newton on xenial

[James Page]

Hi Lars

Apologies; I intended that this go in with the latest set of point
releases for Newton, and then missed this bug as there was no new point
release for Nova at the time.

Uploaded and pushed to the -proposed testing area.

Title:
  nova-api conflicts with nova-placement-api in newton on xenial

Status in Ubuntu Cloud Archive:
  Fix Released
Status in Ubuntu Cloud Archive newton series:
  Fix Committed
Status in nova package in Ubuntu:
  Fix Released
Status in nova source package in Yakkety:
  Won't Fix

Bug description:
  [Impact]
  Upgraders using the consolidated nova-api binary are unable to install and configure the nova-placement-api prior to upgrade to Ocata; this results in a short period where instances creation will be broken (until the placement-api is configured and running).

  [Test Case]
  sudo apt install nova-api nova-placement-api
  <conflict prevents installation>

  [Regression Potential]
  Low; change simply drops the Conflict stanza for nova-placement-api

  [Original Bug Report]
  While attempting to prepare for upgrade to ocata, I ran into an apt conflict between nova-api and nova-placement-api.
