Jonathan Druart cbd375fab7 Bug 15333: Use Koha::Cache to cache exception_holidays instead of a package variable
On the same way as bug 14522, we should use Koha::Cache to cache
exception_holidays.
It's not safe to use a package variable if running under Plack.

There is not test plan, just make sure the changes make sense.
