docs: Add Swagger docs

[hacheigriega]

Motivation

Adding Swagger docs for all query points. To enable it, set swagger = true in app.toml and go to http://localhost:1317/swagger/

To re-generate Swagger docs, run make proto-swagger-gen. Note that client/docs/config.json has to be updated to add or delete query endpoints from the doc.

Closes #159

This feels pretty intense, but then again this is often the case with code/docs generation.

Why do we have to manually check out all dependencies and move their proto files? I tried looking at a few other projects (Gaia and Osmosis) but it seems they don't need/do that?

Yeah the number of lines changed is more than my total changes in this repo 🙃
They do! For Osmosis check: https://github.com/osmosis-labs/osmosis/blob/704e95c88f9742b7515f44262657f7081b5107d5/scripts/makefiles/proto.mk#L39

Aaaah I didn't check beyond their root makefile, that explains :)
