all: remove code that sending heartbeat

Previously, if no logs received after 15 seconds (or any interval user
defined in Config.ForwardInterval), the haminer process send an empty
halog to forwarders (empty halog is the one that use "-" for backend,
frontend, server name, and HTTP method).

This cause bogus traffic and need additional filter when analyzed.
