first commit of ouath test sites, half way through potential breaking change to linkedIn client
LinkedInClient base class changed to OAuth2Client so that scope can be passed in. Not sure if this is going to work so will commit now and potentially revert to OAuthClient base class after
ability to add linkedIn fields to return via Auth config. commit before converting the open source OAuth2 based custom clients (Facebook, Google) to the same format as the LinkedIn custom client (bespoke, OAuth based) (potentially breaking change)
revert back to auth2 facebook client to get stable version for demo
