OP-3939 - added plugin to update tags for thumbnail representation

Integration of thumbnail could be explicitly controlled on one place, overwriting implicit state from host implementations.

+""" Marks thumbnail representation for integrate to DB or not.
+
+    Some hosts produce thumbnail representation, most of them do not create
+    them explicitly, but they created during extract phase.
+
+    In some cases it might be useful to override implicit setting for host/task
+
+    This plugin needs to run after extract phase, but before integrate.py as
+    thumbnail is part of review family and integrated there.
+
+    It should be better to control integration of thumbnail in one place than
+    configure it in multiple places on host implementations.
