Ivan A. Melnikov 6134ff689a Wrapping and serializing failures ...

* save task failures to sqlalchemy backend and restore them
  from there;
* for any wrapped exception use common WrappedFailre exception
  type, which makes it easier to handle particular exception types;
* several minor improvements.

Affects-db: this change adds db migration that looses exception
    information for saved task details.
