nova_migration_target fails to start on compute nodes

[Dan Prince]

Using latest TripleO w/ Podman. I checked my compute nodes and discovered the nova_migration_target fails to startup. Looks like an address in use exception:

[root@overcloud-novacompute-1 tripleo-config]# netstat -tlnp | grep 2022
tcp 0 0 0.0.0.0:2022 0.0.0.0:* LISTEN 5402/sshd
tcp6 0 0 :::2022 :::* LISTEN 5402/sshd

On the host:

[root@overcloud-novacompute-1 tripleo-config]# cat /etc/ssh/sshd_config | grep 2022
Port 2022

----

Puppet is configuring sshd on the host which should not be. Probably a flattening issue with the Nova services?

    Drop step_config from containerized Nova services

    Duplicate 'step_config' sections were added to these services
    during the recent flattening efforts. This is causing Puppet
    to execute on the host which can cause duplicate ssh port
    errors in the case of the nova-migration-target service.
