Consider removing Faraday

[mattheworiordan]

Removing Faraday will reduce the dependencies, but should also allow us to take a little more control over the underlying library.

See excon/excon#682 for example, something we should be able to resolve easily by changing settings, but this is not possible because of https://github.com/lostisland/faraday/blob/master/lib/faraday/adapter/excon.rb#L22-L24.

This may no longer apply given #197 ( https://github.com/ably/ably-ruby/pull/197|smart-link )

@mattheworiordan Do you think we should still remove Faraday? What benefit will this bring to the codebase?
