Fix Http Status Code with Otel Bridge

[alanprot]

HttpStatus code is not working correctly as status code is set as int16 but the otel bridge does not expect int16 attributes. As result, the status code is set as string.

See: https://github.com/opentracing-contrib/go-stdlib/blob/master/nethttp/server.go#L143-L145

This is problematic as the exporters (xray for instance) expects the status code to be set as an int and defaults to 0 if its not.

See: https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/6dc71bd739b4eaa407a9a596dc57ca4884e6313e/exporter/awsxrayexporter/internal/translator/http.go#L57-L59
