Tune OkHttpClient settings

[jorkey]

Hello.
How can I set OkHttpClient properties with binance-connector-java?
I want to enable pings for WebSocket connections.
OkHttpClient has property pingIntervalMillis, that initialized from OkHttpClient.Builder.
But binance-connector-java calls constructor of OkHttpClient with default Builder.

Hi @jorkey,
it's currently not possible to change the default settings of OkHttpClient at WebSocketStreamHttpClientSingleton.

We could explore this in the future, but in the meantime to accelerate the investigation and integration, if you already have an idea on the implementation, feel free to open a PR :)

Hi @aisling-2, thank you for replay.
I tried to solve this problem here #85.
