PR: https://github.com/dataquest-dev/DSpace/pull/647

It is used for uploading big file using a path in v7. Check original issue: https://github.com/ufal/clarin-dspace/issues/1094

Refactoring of uploading the big file is needed: 1. Input field for big file won't be defined in the submission-forms.xml 2. The big file upload step will be added into Upload step - add a two input fields (file path, file description) there - add a button Add file there 3. After clicking on the Add file button the file will be upload

Note: - bigfile Item's metadata won't be deleted after upload - this input field will be allow only for admin - this approach allows the admin to upload more big files - redirectToURL metadata is bitstream's level metadata, not item's

[milanmajchrak]

• The Item's redirectToUrl metadata is removed after every upload
• The cfg property which determines whether the file is removed after upload, was set to false, meaning "do not delete that file."
