Zhengchao An c0e2c02e51 fix(rio): warn once when internode HTTP/2 tuning is inert on plaintext (backlog#805-C3) (#4587) ...

The internode HTTP/2 window/keepalive tuning (apply_http_client_tuning +
http2_keep_alive_* in build_http_client) only takes effect when the connection
negotiates HTTP/2, which happens via TLS-ALPN. Over plaintext internode
transport the connection is HTTP/1.1 and all the tuning is silently inert,
with no signal to the operator.

Make this honest without changing protocol behavior (no h2c, no
prior_knowledge, no opt-in flag):
- InternodeHttpClientTuning gains h2_tuning_explicit, true when the operator
  set a window size, a non-default tuning profile, or the keepalive env.
- Add pure predicate should_warn_h2_inert(negotiated_is_http2,
  h2_tuning_explicit, already_warned) and maybe_warn_h2_inert, gated by a
  process-lifetime AtomicBool so the warn fires at most once.
- Call maybe_warn_h2_inert at both record_internode_http_version sites using
  the actual negotiated resp.version().
- Document the TLS-ALPN requirement at apply_http_client_tuning and near the
  ENV_INTERNODE_HTTP2_* constants.

Tests cover the should_warn_h2_inert truth table and that h2_tuning_explicit
reflects explicit windows and a non-default profile.
