Added the net/speedtest package that contains code for starting up a speedtest server and a client. The speedtest command for starting a client takes in a duration for the speedtest as well as the host and port of the speedtest server to connect to. The speedtest command for starting a server takes in a host:port pair to listen on. Signed-off-by: Aaditya Chaudhary <32117362+AadityaChaudhary@users.noreply.github.com>
