Nazar Gargol eb203de714 Added ability to resize and compress images on upload (#9837)
refs #4453

* On by default

* Added config to disable resizing

* Added basic image optimization processing

* Added dep: sharp (optional dep)

* Added resize middleware

* Take care of rotation based on EXIF information

* Removed all meta data from optimised image

* Added handling if sharp could not get installed

* Do not read ext twice - optimisation

* Do not call sharp if config is disabled

* Do not remove the original image which was uploaded (store 2 images)

* Support of `req.files` for internal logic

* Disabled cache to enable file removal on Windows
