Upstream Writable Gateway Specs

[lidel]

Hi @makeworld-the-better-one @RangerMauve

FYI there is a specs PR with initial attempt to document current behavior of the HTTP gateway provided by go-ipfs 0.13-rc1.
Details / feedback in ipfs/specs#283

Ask 1: please review the spec

• Would appreciate your feedback from your group (as gateway implementers you are intended audience), especially if you feel that something is missing or unclear.

Ask 2: Consider opening PR with Writable Gateway specs

• You prototyped writable gateway behavior (IPIP: Data Onboarding via HTTP POST (and future ipfs:// POST|PUT) ipfs/specs#375) and documented it as POST PUT DELETE in https://github.com/AgregoreWeb/agregore-ipfs-daemon/blob/main/spec.md and this is more than enough to start spec standarization process :)
• Logistics: to get things started:
  • open a PR as a diff against my PR and add WRITABLE_GATEWAY.md to ipfs/specs/http-gateways/. The file would be a delta between PATH_GATEWAY.md and writable ones, so you would only focus on "write" HTTP methods.
