I know what the problem is:
(9:59:34 AM) mriedem: set_inventory_for_provider -> _ensure_resource_provider
-> _create_resource_provider -> safe_connect returns None because it can't talk
to placement yet
(9:59:41 AM) mriedem:

(9:59:44 AM) mriedem: so we put None in the cache

Description
===========
Bringing up a new cluster as part of our CI after switch from 16.1.0
to 16.1.1 on Centos, I'm seeing this error on some computes:

The error seems persistent for a single run of nova-compute.
Steps to reproduce
==================
Nodes were started by our CI infrastructure. We start 3 computes and
a single control node. In 50% of cases, one of the computes comes up
in this bad state.
Expected result
===============
Working cluster.
Actual result
=============
At least one of 3 nodes fails to join the cluster, it's not picked up
by discover_hosts and I see the above stack trace repeated in the
nova-compute logs.
Environment
===========
1. Exact version of OpenStack you are running. See the following
list for all releases: http://docs.openstack.org/releases/
$ rpm -qa | grep nova
python-nova-16.1.1-1.el7.noarch
openstack-nova-common-16.1.1-1.el7.noarch
python2-novaclient-9.1.1-1.el7.noarch
openstack-nova-api-16.1.1-1.el7.noarch
openstack-nova-compute-16.1.1-1.el7.noarch
2. Which hypervisor did you use?
(For example: Libvirt + KVM, Libvirt + XEN, Hyper-V, PowerKVM, ...)
What's the version of that?
$ rpm -qa | grep kvm
libvirt-daemon-kvm-3.2.0-14.el7_4.9.x86_64
qemu-kvm-common-ev-2.9.0-16.el7_4.14.1.x86_64
qemu-kvm-ev-2.9.0-16.el7_4.14.1.x86_64
2. Which storage type did you use?
(For example: Ceph, LVM, GPFS, ...)
What's the version of that?
Not sure
3. Which networking type did you use?
(For example: nova-network, Neutron with OpenVSwitch, ...)
Neutron with Calico (I work on Calico, this is our CI system)
