Update to knplabs/github-api version 2

[MrPetovan]

First of all, thanks for this awesome project!

During install with Composer, it says:

Package guzzle/guzzle is abandoned, you should avoid using it. Use guzzlehttp/guzzle instead.

The guzzle/guzzle package is required by knplabs/github-api:^1.7 but not by knplabs/github-api:2.*.

Is there any intention of using the new knplabs/github-api library version?

I tried a few months ago to update php-github-api to v2, unfortunately I gave up after failing to follow their upgrade path.
It would be very nice to be able to implement such upgrade and to abandon legacy guzzle version.

I understand, I was just wondering if it was known or planned. Thank you for your time!
