Jimmy McCrory 79eb16e44d Filter lxc_images list per host
To greatly reduce the amount of log noise from skipped tasks, when
setting the 'lxc_images' var filter it to only include items that begin
with the 'cache_index_item' var. The when clauses in tasks that looped
through 'lxc_images' looking for this same match can be removed.
