Allows the calling of the UserInfo endpoint to be configurable.

As mentioned in #148, ADFS does not support the email or profile claims, and calling the UserInfo endpoint is pointless, as it only returns the subject.

As the UserInfo endpoint is not required, this PR adds a new config item - call_userinfo_endpoint (default true), which allows the skipping of this endpoint.

Resolves #145

I suggest to keep the default case as is and put this extra handling into elsif !options.call_userinfo_endpoint and a test case would be great.

As far as I can tell, ::OpenIDConnect::ResponseObject::UserInfo.new works on a regular Hash; what's the deal with using JSON::JWS?
