D4977: Download remote icons during initialization of FlatpakResource items

Restricted Application added a project: Plasma.
Restricted Application added a subscriber: plasma-devel.

REVISION SUMMARY
  Remote icons are used by .flatpakrepo or .flatpak files so we need to download them
  to be able to use them later. The icons are downloaded to ~/.cache/discover location
  and either used directly if we have downloaded them before or download is initiated in
  constructor and once the icon is downloaded we let the UI know to update it.
