i18n - Lazy translation unsupported by watcher-db-manage

[Vincent Françoise]

The watcher-db-manage command currently does not support the lazy translation. Since python-cinderclient now uses the graduated oslo_i18n lib, we now have most of the unit tests related to this command fail.

Fix: Make sure the headers are translated before passing them to the prettytable lib (which does not handle it).

    Fix lazy translation issue with watcher-db-manage

    In this changeset, I fix the issue caused by the use of lazy
    translations within the 'watcher-db-manage purge' subcommand.
    This is caused by the PrettyTable dependency which performs
    addition operations to format its tables and the __add__ magic
    method is not supported by oslo_i18n._message.Message objects.
