Show only relevant integrations and automate the setup on Admin

[humitos]

When importing a project for a known service (Gitlab/Github/Bitbucket) the webhook/integration is configured automatically.

Then, going to Admin -> Integrations -> Add integration you have a dropdown to select between:

• Github
• Bitbucket
• Gitlab
• Generic

I'd say that we should only list only the relevant ones: Generic + the one of the known service for that Project.repo URL and I have an account of that service connected.

Also, in case the service connected (and project URL) is Gitlab, if I choose it that webhook option from the list it should be setup the webhook automatically instead of showing something like:

Related to #3932 and also low priority.

What about the people that want to add a webhook to a supported service without connecting their account? Also, wouldn't people think that rtd only supports that provider (the one that is connected to their account)?

In this case (when the project was not imported from a known service) we should show all the options available.

Also, wouldn't people think that rtd only supports that provider (the one that is connected to their account)?

Mmm... This makes me think that even importing a using a connected account, I may want to "depend on another" repository (like Bitbucket) and trigger builds when something in that other repo has changed also.

I think this case it's kind of weird, though.

Anyway, we can close this issue as invalid for now.
