Add Resource UserAuthContext

[simonredfern]

Add new model UserAuthContext

userId: String key: String value : String

Add role CanModifyUserAuthContext Add POST , GET for this resource.

example usage:

userId = "qieuriopwoir987203984729384ipeiu" key = "CUSTOMER_NUMBER" value = "78987432"

userId = "qieuriopwoir987203984729384ipeiu" key = "TOKEN" value = "qieuriopwoir987ASYDUFISUYDF678u"

list[AuthContext] will be added to authInfo / callContext for the purpose of identifying the user making the call. This will give us more flexibility when sending requests to the CBS on behalf of the User.
