this patch adds Koha::Cache functionality to the 'single_holidays' table
it is a performance patch for the problem described in BZ14315, only
http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=14315
it replaces slooow DateTime holiday objects with simple Ymd strings (19991230), then stores the strings in an @array using Koha::Cache
it does not attempt to add caching to all holiday tables - just the single_holidays table (at this stage
on my test (master-cd9a827); nytprof showed a time reduction of the single_holidays() sub - from 61.7s to 587ms
here are some before/after nytprof runs, (really on master-cd9a827, not 3.20)

to test...
1/ add a bunch of single_holidays to your test koha, (my table has 400 holiday rows)
2/ add a loong circ rule for an itemtype (my rule has 140 days)
3/ checkout an item to a user (took me 67 secs)
apply patch...
4/ return item
5/ repeats steps 1..3, (took me 6 secs)
6/ add/change/delete some various single_holidays, via Home->Tools->Calendar
ensure that your various changes have indeed saved correctly
for extra points...
7/ run tests t/Calendar.t and t/db_dependent/Holidays.t, with all tests pass OK
