[Discuss] Merge the comments of a single PR

[morningman]

Is your feature request related to a problem? Please describe.

When we submit multiple comments to a PR, osschat will send each comment one by one. This will cause the WeChat group to be received too many notification.

Describe the solution you'd like

There are more decisions that need to be made to merge comments.

For example, how long should we wait for another comment when we received one comment before we send it to the WeChat room? 1 minute? 3 minute?

How can we implement this feature, for example, how to design a manageable storage structure to deal with those comments?

I'd like to accept a PR for this feature if there's anyone like to submit one, and we can continue discussing based on the PR.
