Add available GithubAppInstallations to a user

[joshsmith]

Problem

We need to find a way to add available GithubAppInstallations for a User that the user has access to for the GitHub App.

We'll have to refresh this data by hitting GitHub's API endpoint for listing a user's installations.

We may want an endpoint for this at our own /user/github-app-installations. We could also consider having this simply be available to a User on the UserView, but this may confuse things with an existing GithubAppInstallations relationship. We could perhaps rename the key to something like available-github-app-installations but keep the type github-app-installation.

Alternatively, we could also rename the user relationship in GithubAppInstallation to sender, which is more in-line with GitHub's own API and can reduce some confusion there.

This could definitely use some thoughts @begedin.

The way I see it, this goes two ways

If this is a relationship we want to store locally, then we need to add it to the user, rename the existing user relationship on the GithubAppInstallation to sender or installer. Add an owner or something as a second user relationship. The user can then have accessible_github_app_installations and installed_github_app_installations.

Then we can deal with it through ember-data and models

If it's something we fetch at one point and simply pass on as JSON to the user, then I see the benefit of having a special endpoint for it. In that case, we should probably be circumventing ember-data as well and simply have a computed filter the data directly.

Either way, I'm leaning against scheduled/periodic refreshes just to store the records locally. If we want to store them, we should identify the cases where they change and store them.

• installation webhook
• upon connecting a user with github
• etc.

Automatic refreshes sound like we're almost bruteforcing it and I don't like doing that until we've exhausted our options.
