    Remove "Resource Providers" upgrade check
    
    With placement being extracted from nova, the
    "Resource Providers" nova-status upgrade check no
    longer works as intended since the placement data
    will no longer be in the nova_api database. As a
    result the check can fail on otherwise properly
    deployed setups with placement extracted.
    
    This check was originally intended to ease the upgrade
    to Ocata when placement was required for nova to work,
    as can be seen from the newton/ocata/pike references
    in the code.
    
    Note that one could argue the check itself as a concept
    is still useful for fresh installs to make sure everything
    is deployed correctly and nova-compute is properly
    reporting into placement, but for it to be maintained
    we would have to change it to no longer rely on the
    nova_api database and instead use the placement REST API,
    which while possible, might not be worth the effort or
    maintenance cost.
    
    For simplicity and expediency, the check is simply removed
    in this change.

Title:
  nova-status upgrade check fails with extracted placement-api

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Currently doing extraction of placement api out of nova. Fresh deployment work fine,
  however while doing an nova-status upgrade check once is up and with instances runningt he Resource Providers check fails due:

  There are no compute resource providers in the Placement service but
  there are 1 compute nodes in the deployment. This means no compute
  nodes are reporting into the Placement service and need to be upgraded
  and/or fixed. See
  https://docs.openstack.org/nova/latest/user/placement.html for more
  details.

  In an IRC chat in #openstack-placement channel, I've been told is
  because upgrade check command looks in the wrong database, and so is
  failing.

  Following logs:
