[Maniphest] [Created] T2566: Refactor ArchiveInterface API with entries metadata

[elvisangelaccio (Elvis Angelaccio)]

elvisangelaccio created this task.

TASK DESCRIPTION
  Currently the `ArchiveInterface` methods require either a `QStringList` or a `QVariantList` with the list of files to work on.
  
  We should replace this with something:
  
  1. More consistent
  2. With more informations for the jobs, i.e. with metadata about the entries
  
  In other words, we need to pass a list of `ArchiveEntry` objects to the API methods. Ideally `ArchiveEntry` should become a proper class and incorporate the `fileRootNodePair` logic.
  
  For example, this will be needed to fix bug #363368.
