Issue #1457
unit.import_content() failure leaves file-less unit in DB
Description
Plugins used to move a unit's files into place and then save the unit in the DB. With 2.8, this had to be reversed.
So if the import_content() call fails, the unit will be left in the database without having files. This is a difficult state to recover from.
A potential solution is to help plugins attempt to undo the save if the import_content call fails. Something like this on FileUnit might work:
diff --git a/server/pulp/server/db/model/__init__.py b/server/pulp/server/db/model/__init__.py
index a6ba85b..6d2454f 100644

Ensure file objects are cleaned up on error
Plugins save then call import_content on FileContentUnit objects. This ensures that if an error happens on import_content, we also clean up after ourselves.
