Pauseless consumption is not compatible with multi-topic ingestion

[lnbest0707]

Both multi-topic ingestion and pauseless consumption are relatively newly added features. Some newly introduced PRs like #14920 did not cover the multi-topic ingestion scenarios. We might need to address them (mostly on metadata processing side) to achieve real "GA" for both. No major changes are expected so far.
