[15/26] tinkerpop git commit: Pass custom headers to the websocket connection

[fl...@apache.org]

Pass custom headers to the websocket connection

In order to authorize to the gremlin server (in this case AWS Neptune) i need to pass custom headers for authorization to the service. the PR will allow to send any headers (like an API key or signature) and pass them to the Websocket function.
While there can be many use cases for this, in my case i pass the Authorization & x-amz-date required for Signature V4 (IAM) authentication.
