With the previous value (10 seconds by default), a connection
established with HTTP long-polling was closed if the server did not
send any packet for 10 seconds (the HTTP request would timeout from the
client side).

It will now default to 1 minute, which is above the
`pingInterval + pingTimeout` value from the server.

Note: the connectTimeout and writeTimeout options are left as is (10
seconds), but you may need to increase them depending on your use case:

```
OkHttpClient client = new OkHttpClient.Builder()
	.connectTimeout(20, TimeUnit.SECONDS)
	.readTimeout(1, TimeUnit.MINUTES)
	.writeTimeout(1, TimeUnit.MINUTES)
        .build();
```
