When queue_event_streamer driver is used and RabbitMQ
is down, stats update processes occupy the thread pool
which is shared with health update processes. Then,
RabbitMQ down unexpectedly leads to delete all existing
amphorae. This commit separates the thread pool and aims
to keep the existing amphorae working even when RabbitMQ
is down.
