https://linear.app/unleash/issue/2-1232/implement-first-iteration-of-the-new-slack-app-addon
This PR implements the first iteration of the new Slack App addon.
Unlike the old Slack addon, this one uses a Slack App (bot) that is
installed to Slack workspaces in order to post messages. This uses
`@slack/web-api`, which internally uses the latest Slack API endpoints
like `postMessage`.
This is currently behind a flag: `slackAppAddon`.
The current flow is that the Unleash Slack App is installed from
whatever source:
- Unleash addons page;
- Direct link;
- https://unleash-slack-app.vercel.app/ (temporary URL);
- Slack App Directory (in the future);
- Etc;
After installed, we resolve the authorization to an `access_token` that
the user can paste into the Unleash Slack App addon configuration form.

This PR updates the OpenAPI schemas for all the operations tagged with
"addons". In doing so, I also uncovered a few bugs and inconsistencies.
These have also been fixed.
## Changes
I've added inline comments to the changed files to call out anything
that I think is worth clarifying specifically. As an overall
description, this PR does the following:
Splits `addon-schema` into `addon-schema` and
`addon-create-update-schema`. The former is used when describing addons
that exist within Unleash and contain IDs and `created_at` timestamps.
The latter is used when creating or updating addons.
Adds examples and descriptions to all relevant schemas (and their
dependencies).
Updates addons operations descriptions and response codes (including the
recently introduced 413 and 415).
Fixes a bug where the server would crash if it didn't recognize the
addon provider (test added).
Fixes a bug where updating an addon wouldn't return anything, even if
the API said that it would. (test added)
Resolves some inconsistencies in handling of addon description. (tests
added)
### Addon descriptions
when creating addons, descriptions are optional. The original
`addonSchema` said they could be `null | string | undefined`. This
caused some inconsistencies in return values. Sometimes they were
returned, other times not. I've made it so that `descriptions` are now
always returned from the API. If it's not defined or if it's set to
`null`, the API will return `description: null`.
### `IAddonDto`
`IAddonDto`, the type we used internally to model the incoming addons
(for create and update) says that `description` is required. This hasn't
been true at least since we introduced OpenAPI schemas. As such, the
update and insert methods that the service uses were incompatible with
the **actual** data that we require.
I've changed the type to reflect reality for now. Assuming the tests
pass, this **should** all be good, but I'd like the reviewer(s) to give
this a think too.
