Auth Handler DSL

[thheinen]

Instead of programmatically define options for authentication handlers, define an easy DSL.

name 'redfish'
desc 'Authentication and Session handling for the Redfish 1.0 API'

option :username, required
option :password, required

login_method  :post
login_path    'SessionService/Sessions/'
login_headers { ... }
login_payload { |auth_options| ... }

logout_method :delete
logout_path   ...

This could result in easy handlers just using the DSL and only more complex ones using the defined interface instead.
