Provide real-time logs

[lachmanfrantisek]

We need to find a way how we can show the logs in real-time.

Some notes about implementation:

• Ideally, logs will be incorporated into the dashboard.
• Can we do this with the current workflow (data for the dashboard are transformed via packit's REST API)?
• Jobs run in workers and use sandcastle pods for running sandboxed commands.
• Do we need logs of all (external/subprocess/sandboxed) commands to be real-time (line by line), or provide all logs for each command after the command ends?

This is a part of our UX effort to provide more information to users about the process of ongoing packit-service jobs.

This absolutely needs some research - we need to find out how other projects are doing this (e.g. zuul).

For me the most natural way would be to use websockets.

This epic is a bit outdated, there wasn't any demand for the real-time logs and we have other epics with higher priority. I am closing this and we can easily reopen if requested/needed.
