Remove dependency on faraday_middleware

[wheresrobert]

faraday_middleware is deprecated.

https://github.com/lostisland/faraday_middleware

qbo_api is the only gem in my project that depends on faraday_middleware, which in turn, prevents upgrading of faraday itself.

Thanks for the heads up. Taking a look.

FWIW: I did just release v2.1.0 that locks in Faraday 1.10.x until I'm able to get off the middleware the gem is using.

Notes:

The qbo_api gem is utilizing two aspects of thefaraday_middleware gem:

1. A homebrew middleware "RaiseHttpException" module that inherits from Faraday::Middleware;
2. and the OAuth2 middleware included in the faraday_middleware gem.

If anyone would like to tackle these two?

Closing. Version 3.0.0 removes faraday_middleware dependency.
