Rocky Ceph/SUSE builds fail due to missing ceph_uid

[Jesse Pretorius]

OSA stable/rocky uses the stable-3.1 branch of ceph-ansible. When building, the following task failure happens:

2018-11-26 17:28:49.842602 | opensuse-423 | TASK [ceph-defaults : create ceph initial directories] *************************
2018-11-26 17:28:49.952237 | opensuse-423 | fatal: [aio1_ceph-mon_container-20aa8631]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'ceph_uid' is undefined\n\nThe error appears to have been in '/etc/ansible/roles/ceph-ansible/roles/ceph-defaults/tasks/create_ceph_initial_dirs.yml': line 18, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: create ceph initial directories\n ^ here\n"}

In the ceph-ansible stable-3.2 branch, this is resolved by https://github.com/ceph/ceph-ansible/commit/7172737f13cba38c8a80f1ad99c091c8726af9b9

Once there is an equivalent patch which fixes the suse/ceph builds for rocky, we can re-enable voting for the job.

    Set SUSE ceph-distro job to non-voting

    In https://review.openstack.org/616481 we switched OSA stable/rocky
    from ceph-ansible 3.2 to 3.1, but https://review.openstack.org/614463
    made the job voting before that merged. The 3.1 builds for SUSE do not
    work (see related bug), so we switch this job to non-voting. Whenever
    the issue is fixed upstream, we can revert this (and add the missing
    gate job too).
