Handle HTTP2 GOAWAY

[arnaldopereira]

This one might need a little investigating: sometimes ette receives GOAWAY from the node and handles that as any type of error. An example log message follows:

Post "https://mainnet.infura.io/v3/x": http2: Transport: cannot retry err [http2: Transport received Server's graceful shutdown GOAWAY] after Request.Body was written; define Request.GetBody to avoid this error

IMO ette shouldn't handle response errors generically, this might be the real issue here.

It's HTTP2's connection graceful termination initiated by server. Probably it rather than brining self down, connection retry can be attempted.

What're your thoughts ?

I've stopped maintaining ette, so closing this issue. Thanks.
