isisd, ospfd: IGPs detect LDP down via zapi client close message
When ldp-sync is configured, IGPs take action if the LDP process goes down.
Currently, IGPs detect the LDP process is down if they do not receive a
periodic 'hello' message from LDP within 1 second.
Intermittently, this heartbeat mechanism causes false topotest failures.
When the failure occurs, LDP is busy receiving messages from zebra for a
few seconds. During this time, LDP does not send the expected periodic
message.
With this change, IGPs detect LDP down via zapi client close message.
