Enhanced the authentication/:id/import_users interface for a more user-friendly user import feature:

• Add new parameter ?type=plain to support importing users with plaintext passwords in addition to the current solution which only supports password hash.
• Support content-type: application/json to accept HTTP Body in JSON format in extension to the current solution which only supports multipart/form-data for csv format.
