Fixes #7402

Brief Description

How Did You Test This Change?

通过判断consumerTable的数量判断是否有消费者存在

1. 在初次启动的时候，如果是注册的消费者，则直接将那几个服务启动，否则不启动
2. 如果初次启动不是消费者，但是后续有加入新的消费者，则判断那几个服务是否已经启动，如果没有则启动

Determine whether there are consumers by judging the number of consumerTables

1. At the initial startup, if it is a registered consumer, directly start those services, otherwise it will not start.
2. If the initial startup is not a consumer, but new consumers are added later, determine whether those services have been started, and if not, start them
