how to check health of the connection?

[deamonwatcher]

when i create a new client，how can i check health of it ?
In Apple Privider Api Doc, it said: "You can check the health of your connection using an HTTP/2 PING frame." In your "Push" fuction, you said:
"If the underlying http.Client is not currently connected, this method will attempt to reconnect transparently before sending the notification."
so, did i need do something else to keep alive of the connetion?

Because we use the higher level HTTP Client which is designed to abstract the complexity of the underlying HTTP/2 connection and make it look like standard HTTP, currently there is no way to check the health of a connection.

That said, If you init a apns2.Client and hold on to it, it will stay open until something happens (network connection drops etc). In the advent that it does drop, it would just transparently re-connect the next time you call Push() and stay open again.

Theoretically you could do this if you dropped down to using x/net/http2 ping frames etc, but we haven't yet needed to do so. Just keeping a handle on the apns2.Client should be sufficient.

See #45 for a potential solution.
