Query batching

The bundle supports batching using ReactRelayNetworkLayer or Apollo GraphQL directly. To use batching, you must use "/batch" as a suffix to your graphql endpoint (see routing config). Then you can switch between implementations in your configuration like so:

For Relay (default value):

overblog_graphql:
    batching_method: "relay"

For Apollo:

overblog_graphql:
    batching_method: "apollo"

Done!
