http server: limit max concurrent requests (#4185)
* lib/httpserver: introduce `-http.maxConcurrentRequests` command-line flag

Introduce `-http.maxConcurrentRequests` command-line flag to protect
VM components from resource exhaustion during unexpected spikes of HTTP requests.
By default, the new flag's value is set to 0 which means no limits are applied.
