Store images in DB

[abelfodil]

Is your feature request related to a problem? Please describe.
I have a multi-node cluster and whenever the node Gotify is scheduled onto changes, I need to copy data folder to preserve favicons. I'm using postgresql to preserve configuration wherever Gotify is scheduled on the cluster. However this doesn't apply to images and I think this is a quality of life gap.

Describe the solution you'd like
I would like Gotify to store blobs in database and not directly on disk.

Describe alternatives you've considered
I considered either scheduling Gotify on a fixed node or having a multinode disk to sync configuration. However as a user, I would like to keep things simple and not have to think about scheduling or GlusterFS like solutions.

Ahh sorry, must have overlooked this. Sounds reasonable and the migration of existing images shouldn't be that difficult
