[fileupload] Have a FileUpload release (after 3.5 years)

[Christoph Grüninger]

Dear Apaches!
 
Apache FileUpload saw its last release in December 2018. Since then security 
issues have been found in some dependencies and the Jakarta namespace was 
introduced. More improvements are part of trunk.
 
What needs to be done to get a FileUpload release out of the door? What kind of 
help can we users provide? What needs to be done by Apache developers?
 
It's not only me, but Apache Wicket, Jenkins, Piranha Cloud and some more:
https://issues.apache.org/jira/browse/FILEUPLOAD-309
(and similar -343, -345).
 
Kind regards,
Christoph
