COMPATIBILITY NOTE

Please make sure that this change is BACKWARDS COMPATIBLE and a new server will work correctly with clients using old APIs versions.

It may be that data sent in the new format will break the old clients.

In case of any potential incompatibility we have to inform our clients and schedule release & deployment with them.

@acc-logging-team - please have a look for approval.

Here we go again, now Java11 is provisioned on our TEST/STAGING machines. Once this is merged in you should run

ansible-playbook -i inventory/dev-<you> openstack-install-with-sudo.yml --vault-pass .pass

On your dev envs.
