Docker compose multiple storages

[pavolloffay]

#493 introduced docker-compose for cassandra storage.

Further improvements could include support for ES storage. We could have one compose file for jaeger services and one compose file per storage. Storage compose file would define (configs)[https://docs.docker.com/compose/compose-file/#configs] which would be used in the main compose file (Similar what we did in k8s jaegertracing/jaeger-kubernetes#53).

Once this is done we could run crossdock against different storages.

Looks like we have integration tests for ES, but do we have cross dock running against ES?

I think we should not be running crossdock against any real/heavy storage. We have storage integration tests. End to end tests don't add much to that, since their goal is testing connectivity between components.

But we do need external storage to be shared between collector and query. The path I see is

• badger PR
• grpc storage API
• run badger behind that grpc API as standalone component
