kennethreitz 2b4a557456 Add metrics, server-side sessions, query-param validation, resp.render ...

- API(metrics_route="/metrics") serves request counts and latency
  histograms in Prometheus text format, zero dependencies. Labels use
  route patterns to bound cardinality; the collector sits as middleware
  outside the exception layer so errors record real status codes
- API(session_backend=...) stores sessions server-side (Memory/Redis
  backends, or any get/set/delete object) with only an opaque ID in
  the cookie — revocable, unbounded size, handler code unchanged
- @api.route(..., params_model=Model) validates and coerces query
  strings with Pydantic: 422 on failure, req.state.validated_params,
  repeated keys map to list fields, documented in the OpenAPI spec
- resp.render(template, **context) renders a Jinja2 template as the
  HTML body in one call
