A validation error when a file is uploaded with a size exceeding permitted limit

[muralivenneti]

UX builder should have an ability to throw a validation error when user attempt to upload a file of size exceeding maximum permitted limit. Currently it creates a work object and discards attachment creation in chorus without an indication to the user of attachment creation failure. Ideally a validation error should be displayed to the user upfront and should not create work object until validation is corrected.
