[Feature] Remove MinIO (memory consumption)

[codeurimpulsif]

Is your feature request related to a problem? Please describe

MinIO is OOM killed every 2 or 3 days, cleaning storage now take a lot of time while before it takes only 10 minutes.

Describe the solution you'd like

I think we can try to remove MinIO and just use Django to access files from other servers. This also remove a dependency to S3 storage.

Describe alternatives you've considered

• Using another S3 storage software like Garage

Additional context

Since last versions MinIO use a lot more memory and is OOM killed every 2 or 3 days.

MinIO seems to focus on big Kubernetes stuff and not small infrastructures anymore, closing all issues about this memory consumption with a "MinIO preallocates buffers for incoming data now" message.
