Removal of Faraday dependency breaks error handling

[stevenringo]

Commit 3be4ea, release 1.3.0 refers.

Unless I am mistaken, the main OAuth2 gem as it stands (still) uses Faraday and removing Faraday here breaks any error handling raised by Faraday in the OAuth2 gem.

Yes, OAuth2 uses Faraday and it doesn't look like it's doing any error handling of it's own: https://github.com/intridea/oauth2/blob/0ab3c213f7baa43f232eb18fa46301e1a9460f7d/lib/oauth2/client.rb#L54

Are there plans to remove faraday from OAuth2, or is this a regression?
