Client connection events

[mistic]

Guys ( @Urigo @DxCx @helfer @dotansimha @NeoPhi ) this issue is to allow us think about the events we are throwing during the connection handshake between the client and the server. At the moment we are only emitting a single event called connect or reconnect when the onopen callback runs. In my opinion we should do this:

• emit a connecting or reconnecting event (according it is a connect or reconnect situation) when the onopen callback runs
• emit a connected or reconnected event when we receive the GQL_CONNECTION_ACK.

What do u think?

Sounds good @mistic .
I think it will also help to implement an good client side indication for the socket status (connecting/connected/disconnection/reconnecting)

@mistic would you want to open a PR?
We might even get this in for the next release

@Urigo @dotansimha I'll open a PR for this. I'm just finishing something even more important so I can open another PR before this one.

@Urigo @dotansimha It's done. Please check #139. I think we can add the label waiting for release
