You should be using the plain hiera() function instead of hiera_hash().
The latter is for collecting values of the same key from multiple levels of
your environment, and returning the combined result as a hash (level =>
value, IIRC). You just want the value assigned to key 'apache'; that the
value happens to be a hash is irrelevant.
