Request descriptions

[ZephSibley]

I think it would be great if we could add descriptions to requests in addition to names/labels.

Ideally the description metadata would get included in generated docs. and perhaps the field could support markdown.

Well, since already we've label field, it would be an overhead in terms of design space to add another meta field. Anyways, will think about it if further requests come. 👍
