What to do with tags?

[wafflespeanut]

tags are useful for grouping operations for displaying in the UI, but how can we use them for client-side codegen? Also, is there a neat way to generate them in server-side?

I'm trying out the actix-web plugin on quite a large api and tags would be really useful for grouping in the UI. Our handlers are already grouped into modules and so I think that would be a natural way to produce the grouping, ideally describing the tag with an inner macro attribute (but this doesn't exist yet - https://github.com/rust-lang/rust/issues/54726)

#![api_v2_tag(
    name = "Tag name",
    description = "Tag description",
)]

#[api_v2_operation]
pub async fn handle_1 ...
#[api_v2_operation]
pub async fn handle_2 ...

For actix-web plugin, we have an approach in #219
