Bug 24152: Add the ability to purge pseudonymized tables

anonymized_* tables have been added by bug 24151, this patch adds the
usual way to purge data from them.

The cleanup_database.pl script has been adjusted to take new parameters
that will help to delete pseudonymized data.

Test plan:
Call the scrip with the new parameter to remove pseudonymized data
* --pseudo-transactions DAYS will remove entries from pseudonymized_transactions older
than DAYS day
* --pseudo-transactions can be used without the parameter DAYS but with
-- pseudo-transactions-from and/or --pseudo-transactions-to instead, to provide a
range of date

You can use the patch from bug 24153 to make the tests easier, data will
not be deleted if the new --confirm flag is not passed.
