This patch introduces a new telemetry connection socket and handling functionality. Like the existing telemetry implementation (which is unaffected by this change) it uses a unix socket, but unlike the existing one it does not have a fixed list of commands - instead libraries or applications can register telemetry commands and callbacks to provide a full-extensible solution for all kinds of telemetry across DPDK.
