docs: add missing ReST :ref:
Add SingletonImportTask

The goal of this class is to eliminate all checks for `task.is_album`. This is
already accomplished for the methods. Next, we want to tackle the plugin
stages.
Add task.apply_metadata() method
Album tasks always record their progress
Add SentinelImportTask and move code into it
Make _resume() session local and refactor resume in read stage

Functionaly, this should not change anything.
Refactor finalize stage into Task class
