Entity Note: It doesn't make sense to handle attachments on Note::create.
Attachments exist out of Notes, they are a thing on their own.
Furthermore, they aren't always handled the same, they most definitely
aren't always uploaded files.
FileQuota: It doesn't make sense to check if a file is greater than max
allowed upload size here. The plugin ensures a user is inside his
allowed quota, it's ignorant to anything else. Whether a file respect
max upload is a core thing that must be handled directly in the Posting
component. TODO: The configuration regarding user and monthly quota
must become FileQuotaPlugin settings and be removed from core.
