Websocket connection closed

Following up on this issue: #29
What's the best way to prevent "Connection closed" happening for a websocket?

[woniesong92]

the connection closes with the message: connection not open on send()

@egalano from the server side, is pong() supported?

AFAIK the client side should just do something like this, right?

setInterval(() => {
  ws.send('__ping__');
}, 30000)

@woniesong92 I feel like this is something the web3.js client should handle for you so you dont explicitly have to do this in your code. Would you be interested in collaborating on a PR?
