Added Rubocop, upgraded Faraday, removed Gemfile.lock.

This is a bunch of related things.

• Removed Gemfile.lock, this is a library it shouldn't rely on fixed locked gems, but only on its declaration in .gemspec - people using hyperclient don't get that lock-in.
• Added Rubocop, automatic style guide, cleans up common Ruby issues and nobody needs to argue about code style anymore ever.
• Replaced faraday digest implementation with https://github.com/bhaberer/faraday-digestauth.

I'm 👎 on this since this gem seems a blatant rip of the actual code at hyperclient. See a47d7db and e443018#diff-05401ebefab536882f566b668412c798L2 vs bhaberer/faraday-digestauth@d41137a

Also, the gem author forgot to copy the tests.

Well, actually it's a rip from https://gist.github.com/kapkaev/5088751 :(

I think this doesn't really belong in Hyperclient and is a generically useful Faraday thing - who copies from whom is beyond the point, no? I guess I am trying to say that instead of adding this code to Hyperclient someone (you? :)) should have made a gem out of this. Looks like @bhaberer did just that (and thanks).

Do let me know if you want me to undo this, though.

I made a PR into the gem acknowledging where it comes from and porting tests, bhaberer/faraday-digestauth#6.

[bhaberer]

Yea the person who posted the gist never responded to any messages so I had no idea that this came from someplace else.

I'll merge that pull in a bit, and add @oriolgual as a gem author, if he wants?

I'm fairly amicable to whatever. I just need/ed Faraday to speak digest.

[oriolgual]

That seems super reasonable, thank you both :) and 👍 on this PR
