apachesync - delete sync-apache script

the sync-apache script(s) are not needed anymore
because Apache config is now deployed by puppet

in I69150281fb08a Ori suggested to remove this entire module,
but we pointed out how we still want to keep apache-graceful-all
(which we wanted to change from dsh to salt) and how apache-fast-test
is still a useful test script we'd like to have

so this first deletes the obvious to make the module smaller,
then we can see to move the other 2 scripts elswhere and then
delete this module
