• Split ElasticSearch fro api-umbrella to separate container.
• Make ElasticSearch available only from private docker network (between containers).

Closes #1249

Should we also be depending on Elasticsearch 2.x.x?

ElasticSearch 2 allowed, but by default api-umbrella use 1.7.5. Because we will migrate on use API instead of direct call to Elasticsearch, I decide keep default version.

But if you see any scenario where it will be useful I can migrate on 2.x.x

[brylie]

Well, lets go ahead and migrate to Elastic 2 now. It changes our analytics schema slightly, so we can make the changes sooner, rather than later.

@brylie After migrate to ElasticSearch 2, api-umbrella dashboard works OK (Analytics), but apinf-umbrella-dashboard dose not show data. Tomorrow will check with @marla-singer

[brylie]

OK, thanks @shaliko. We may need to make an update to our dashboard code, to match the Elasticsearch data structure.

Please add the Ready for revies tag once you have spoken with @marla-singer

@brylie In debug session with @marla-singer we found the root case of issue:

"reason": "Result window is too large, from + size must be less than or equal to: [10000] but was [50000]. See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the [index.max_result_window] index level parameter."

For work with old releases (docker images) I will add increase "max_result_window" on start ElasticSearch. But I am not sure that we really need 50000 value.
