Async ping to hosts

[erolfedakar]

Hello,

I am trying to make async ping to hosts, in current we are sending ping all at the same time,

so I want to do first try ping to first hosts when getting a reply from first hosts to try second hosts,

in current sending ping to all hosts same time.

It should work for using with promise ping. In your case, you need something like a waterfall or series implementation. Here is the idea from bluebird

http://bluebirdjs.com/docs/coming-from-other-libraries.html#async.waterfall

Bluebird is simply a library for working with promise object. You can choose whatever promise library you like.
