freezer doesn't work when deployed

[Marek Grudzinski]

Deploying freezer out of the box expects elasticsearch 2.3.0 (according to freezer docs)
Kolla-ansible deploys elasticsearch with 5.6.x
Due to this freezer is deployed onto elasticsearch 5.6.x it won't work since it uses older query types.

Freezer could be used with mariadb/mysql instead. It would be more suitable for an out-of-the-box solution for kolla-ansible and let users to deploy it towards elasticsearch with options, even if its the better option (scalability).

I'm not sure that deploying a secondary elasticsearch (in kolla-ansible) out-of-the-box just for freezer is suitable, but also an option.

I'll submit a change to use the existing mariadb as default with options to point out an external (compatible) elasticsearch.

Do you have any errors related to freezer on horizon UI? When I am trying to open it - Error: [*] Error 500: search operation failed: TransportError(400, u'parsing_exception', u'no [query] registered for [filtered]')
