base-context initialization

[gersak]

Hi,

This pull request addresses 2 changes.

First one is support for graphql-ws protocol specification: https://github.com/enisdenjo/graphql-ws/blob/master/PROTOCOL.md that is supported in newer versions of GraphiQL

Second one is base-context initialisation for connection-loop. Currently in subscriptions namespace there is no other way to extend base-context and include some ws request params data into base-context that connection-loop will use to process incoming GraphQL subscription request.

Why? Authorization i.e. If access_token is sent during ws establishment and user info (roles, groups) are important for subscription execution, base-context feels like logical place to hold that information. Since it is available to all subscription resolvers. Right?

If I misunderstood current codebase i apologise and would be really grateful if u could show me workarounds.

Thanks,
Robert
