Update composer.json to use guzzlehttp about slackbundle

[DZunke]

Hey,

thanks for your hint. I will have a look at it in a few days along with some other changes to create a v2 tag. Hopefully i will be able to deliver it at the end of the next week, at latest!

"dev-2.0-dev" has been running in prod on my site for a while now - admittedly, with very light traffic - but there's been no issues for me with the bundle/code. If you wanted to make a 2.0.0 release, I'd happily update my own composer.json for it.

Sorry for delay. I have created a new branch 2.0-dev to create some Non-BC changes. The Guzzle upgrade to v6 is already included and should work if you want to try it 😄

I've got it working (at least, it sends a message via bin/console dzunke:slack:message), however there were two issues:

1. I was being caught by my home ISPs proxy page before it would redirect to the secure URL, but adding endpoint: "https://slack.com/api" to the config sorted that (making it the default in getConfigTreeBuilder() may be useful).

2. In Slack\Client\Response::parseGuzzleResponse(): Just $guzzleResponse->getBody(true), returns a GuzzleHttp\Psr7\Stream, so ....

   // To return the contents of the response, decoded
   $responseArray = json_decode($guzzleResponse->getBody()->getContents(), true);

   // Also usefully, PHP 5.6+ allows for:
   use function GuzzleHttp\json_decode;
   // Wrapper for json_decode that throws when an error occurs.

Thanks for all your efforts.

I've made #16 with the two changes

Thanks for the MR. I think all is working now. My test.php is working. Missed that i'd used https and haven't added it to the defaults. Sorry!
