API login request with expiring=false now returns feedback

[gwiedeman]

Description

Previously, if you tried to send a curl request with expiring=false, it would return successful regardless of if the param was successful. For example curl -s -F password="admin" expiring=false "http://localhost:8089/users/admin/login" would return successfully, but the token would expire because it should be `curl -s -F password="admin" "http://localhost:8089/users/admin/login?expiring=false"

Now, when you send the expiring param the correct way, the response will include a expire_after_seconds field which shows the number of seconds until the token expires. This is set by AppConfig[:session_nonexpirable_force_expire_after_seconds]
