[storage] Set up automatic deletion of old media

[frgfm]

For now, the media that are uploaded to the bucket are stored indefinitely. But in the long-term, we need to erase those to avoid filling up the disk.

If that's alright with everyone, I suggest setting a MEDIA_PERSISTENCY value in the config (default 30-60days).

What do you think?

Hi there,

This is indeed a good idea ! Moreover, with regard to the CNIL, it is important to define a storage period for our images.

Concretely, how do you want to implement it ?Is the concept to set up a CRON on a backend script deleting old media ?

About the storage period, is 30 days enough time to potentially do training sessions on vision side ?

Good question, I'm not sure how we could do this 🤷‍♂️

We'll let the vision team know, but let's work with the maximum legal duration allowed to give them the best flexibility 👍

FYI, moving this to a later release, since the problem won't be critical before our first live alerts

FYI found a service that could help us do that https://posthook.io/
(found here https://free-for.dev/, sharing because it's nice)

Wrapping my way around this, apart from our current process of doing it manually, the only viable way we could do this is with a cron job :)

Not a priority since we have limited traffic, I'll move this to a later release
