Subject: [PATCH] feat(client): add `http2_max_local_error_reset_streams`
 method to legacy client

Expose the h2 `max_local_error_reset_streams` setting on the legacy
client builder, allowing users to configure the maximum number of
local resets due to protocol errors.

Requires hyper 1.9.0 for hyperium/hyper#4021
