…ment_data field" This change ends up being *mostly* backwards compatible since we still store the url, though this will be basically useless in the future. Attachment size is currently hardcoded to 8MB, in the future this should be able to be set by users.

Moves the attachment handling code to its own class and creates a new abstract class to allow different handlers in the future
Uses the MinIO S3 library

Should include tag for bot ID to help people that are sharing a bucket between multiple bots that they host

As a note for use, Cloudflare and Backblaze both offer 10GB free on their S3 cloud storage systems (R2 & B2, respectively). Cloudflare has no egress fees and Backblaze has some only if you don't route through a CDN and download more than you store. |
…ia config The max size isn't automatically updated when the config is changed. The size is should always be retrieved from the attachment handler and not the config, as the attachment handler may have additional constraints

Add noop attachment handler so the option to not save attachments exists. |

Ability to set retention period for mongodb storage may also be desired |
Adds an attachment handler interface and 2 new clients which implement it.
MongoAttachmentClient: stores attachments as binary data in a mongoDB document in the attachments collection
S3AttachmentClient: Stores attachments as S3 objects in an S3 service of the users choice.
