Allow configuring max_local_error_reset_streams

[alexanderrilee]

Motivation

This makes max_local_error_reset_streams configurable. We have an isolated environment where we create and close many (valid) short-lived gRPC streams. We very quickly hit the 1024 limit on stream resets, which initiates a GoAway. During connection recreation, the Python gRPC client misbehaves. We would like the option to tune this limit, since this is a safe traffic pattern for us.

Solution

I've added http2_max_local_error_reset_streams to the Server API.
