[NEW] Rocket.cat message for users when an app previously requested is installed

[matheuslc]

Proposed changes (including videos or screenshots)

This PR adds a new cronjob to notify end-users that an app they requested is now enabled. The cronjob is scheduled to run every 24 hours after the workspace started. I'm using this strategy to avoid many workspaces hitting marketplace-api at the same time.

Also, worth to mention, this long polling strategy was chosen as we can have many users waiting for notifications, so it's a process-heavy task that it's better to do in the background.

Issue(s)

Task

Steps to test or reproduce

Right now, it's only possible to add app requests through the marketplace API. So, we need to wait for the final version of apps requests to land in staging to staging testing properly.

Great work! I'd like to see this moved to 12 hours instead of 24 hours, that way there isn't too long of a delay.

Looks good from the Marketplace perspective.

Changes made.
