mongodb bootstrap cluster not run

[Eric Miller]

Environment:
Ansible 2.7.8 (latest as of March 16, 2019)
CentOS 7.5.1804 on Kolla-Ansible deployment machine
Kolla-Ansible 7.0.2
Same issue exists in 8.0.0.0b1 since this file hasn't changed since 7.0.0

In the MongoDB handler here:
https://github.com/openstack/kolla-ansible/blob/a9def6ce4b19095e36de11d3cbe461067043054d/ansible/roles/mongodb/handlers/main.yml#L39

The "include_task" is not run, possibly due to this bug in Ansible:
https://github.com/ansible/ansible/issues/20493

So, the ReplicaSet is not created.

The attached patch file fixes the issue, but uses the deprecated "include" plugin, which is supposed to be replaced with include_task, but include_task doesn't work in handlers due to the Ansible bug. This is the only workaround I found.

Unfortunately, this won't be fixed, since MongoDB support has been removed. Release note section below:

    In Victoria support for
    deploying MongoDB will be removed from Kolla Ansible. Note CentOS 8
    already lost support for MongoDB due to decisions made upstream.

    This affects Panko as it will no longer be possible to get automatic
    deployment of MongoDB database for it. However, the default, SQL,
    backend is and will be supported via MariaDB.

    MongoDB lost its position in OpenStack environment after
    controversial relicensing under their custom SSPL (Server Side
    Public License) which did not pass OSI (Open Source Initiative)
    validation.
