Implement RFC 574

[thefringeninja]

Added: Set grpc.max_receive_message_length to 17MB
Fixed: Force Rediscovery Only when Lost Connection or Unknown error

EventStore allows events of up to 16mb to be written internally. While you can't write events this large through gRPC, you could do so through the TCP client, or through projections. To allow the gRPC clients to read any event that EventStoreDB was able to write, we want to hardcode the max receive message length for all gRPC clients to 17mb.

Some cases where redicovery should have been forced were not handled, are handled now.

Fixes #193

• the size restrictions look good
• adding a ReconnectionRequired type looks good

but im suspicious about

• rediscovering on 'aborted' status
• the number of InnerExceptions to dig through - we might need that extra one that was there before because of the typedexceptioninterceptor

[timothycoleman]

The 'aborted' thing is resolved now (rfc is adjusted or in the processof)

I think still need to address the number of InnerExceptions we are looking in to find the RpcException, because the TypedExceptionHandler will wrap it in an InvalidOperationException. If I'm right then UNAVAILABLE will not trigger rediscovery

[timothycoleman]

For documentation we should explain that we aren't wrapping in InvalidOperation exception any more

[timothycoleman]

nice 👍

[timothycoleman]

only couple of tests to update

Wait a moment, why are we dropping InvalidOperationException support? It's also not aligned with a recent @hayley-jean suggestion: https://github.com/EventStore/architecture-and-planning/pull/106
