SAML2 federated authentication for ADFS.

Browse Source 
Authentication workflow for the Active Directory Federated Services
(ADFS) by Microsoft is different from 'standard' ECP based one.
This plugin allows for authentication and fetching security token with SAML2
assertion inside, sending to the Service Provide and retrieving an
unscoped token.
