Sourcegraph Extension for Deploying Code

Created by: yevbar

Feature request description

A Sourcegraph extension for deploying code onto a platform (e.g. now, Heroku)

Is your feature request related to a problem? If so, please describe.

I would like to be able to come to a repository on GitHub and deploy an instance of whatever the repository is holding (for testing purposes or out of general curiosity)

For now, this can be done by taking the URL of the current page, spinning it around for api.github.com, and then using the content of the files.

With Heroku, this could be done if there's an app.json file in the root directory of the project. Heroku has written a post about this

Describe alternatives you've considered.

The services I noted above have GitHub integrations through their systems but it does not flow as smoothly with the code browsing experience on a code host (stumble onto a repository, find it interesting, deploy!)

Additional context

Sourcegraph extensions should flow with the developer experience of floating around a code host or locally hosted Sourcegraph instance. In addition to searching through dependencies and viewing code coverage, I should be able to deploy/view code in action.
