social login linkedin flow is broken and needs updating

[brutif]

The Linkedin support in socialLogin-1.0 has quit working, due to linkedIn removing their v1 apis. Code needs to be updated to use v2 api's.

Error messages now seen:

[5/22/19 0:39:19:370 CDT] 0000003d com.ibm.ws.security.social.tai.TAIUserApiUtils               W CWWKS5461E: The social login feature encountered an error while getting user information from the user API [https://api.linkedin.com/v1/people/~:(firstName,id,lastName,email-address)] that is configured for social login configuration [linkedinLogin]. CWWKS5490E: Cannot process the response from the [https://api.linkedin.com/v1/people/~:(firstName,id,lastName,email-address)] user API endpoint. The response status was [410], error was [{
  "errorCode": 0,
  "message": "This resource is no longer available under v1 APIs",
  "requestId": "QZ2D0SDMNY",
  "status": 410,
  "timestamp": 1558503558326
}] and the error description was [null].

So I took a guess and changed the userApi attribute to specify "v2", but that doesn't work either:

[5/22/19 14:36:34:647 CDT] 000000f7 com.ibm.ws.security.social.tai.TAIUserApiUtils               W CWWKS5461E: The social login feature encountered an error while getting user information from the user API [https://api.linkedin.com/v2/people/~:(firstName,id,lastName,email-address)] that is configured for social login configuration [linkedinLogin].

The response status was [403], error was [{"serviceErrorCode":100,"message":"Not enough permissions to access: GET /people/~:(firstName,id,lastName,email-address)","status":403}] and the error description was [null].

it's not jumping out at me from the github docs how to get this working again
