Descriptive summary

We currently -- since #1821 was merged -- have the ability to define the following limits for the file upload widget:

• Max size of individual file
• Max size of group of files
• Max number of files

This brings Sufia master to parity with Sufia 6.x, with limits defined in JavaScript and enforced by the client. Quoting @atz:

For robust file handling and avoidance of OOM/resource depletion, we need:

• server side limits and proper handling there, e.g. in CarrierWave
• should be configurable
• client limits should take their values from (or be derived from) the server-side ones.

Alternatively, we can just be open to anybody crashing our processes with multi-TB web uploads and delete the js declarations.

(No, let's not be open to that.)

Pertains to Sufia master.

Closing this issue since it is an older enhancement issue that does not seem to be as needed in the community.
