Update from deprecated aws-sdk bindings

[thomashoneyman]

Fixes #629. I manually verified that the inputs (params we pass to the s3 object) and outputs (data we receive) are unchanged in the new SDK, but I haven't actually run this code against our live bucket because the giant legacy importer run is going.

Now that you're also online we can merge this and eventually revert it real quick if it's broken 😄

I was actually putting together a little script to upload, download, and delete an object in storage to be sure before I merge :) Let me give that a quick try and if it works I'll merge! I'll need about 1.5hrs before I can do it.

Ah that's lovely, thank you 🙂

Ran this script to test things out, with a tarball at delete-me-1.0.0 locally:

ain :: Effect Unit
main = launchAff_ do
  -- Environment
  _ <- Env.loadEnvFile ".env"
  resources <- Env.lookupResourceEnv
  s3 <- lift2 { key: _, secret: _ } (Env.lookupRequired Env.spacesKey) (Env.lookupRequired Env.spacesSecret)

  let
    cache = Path.concat [ scratchDir, ".cache" ]

    work = do
      Storage.upload (unsafePackageName "delete-me") (unsafeVersion "1.0.0") (Path.concat [ scratchDir, "delete-me-1.0.0" ])
      versions <- Storage.query (unsafePackageName "delete-me")
      Console.log $ "Versions (uploaded): " <> String.joinWith ", " (map Version.print (Set.toUnfoldable versions))
      Storage.download (unsafePackageName "delete-me") (unsafeVersion "1.0.0") (Path.concat [ scratchDir, "delete-me-2.0.0" ])
      Storage.delete (unsafePackageName "delete-me") (unsafeVersion "1.0.0")
      versions2 <- Storage.query (unsafePackageName "delete-me")
      Console.log $ "Versions (deleted): " <> String.joinWith ", " (map Version.print (Set.toUnfoldable versions2))

  work
    # Storage.interpret (Storage.handleS3 { s3, cache })
    # Log.interpret (Log.handleTerminal Verbose)
    # Except.catch (\e -> Run.liftEffect (Console.log e *> Process.exit 1))
    # Env.runResourceEnv resources
    # Run.runBaseAff'

This works just fine with the v2 of aws-sdk:

However, it turns out that the Contents key is now optional in the response; with that fixed this PR works as well.
