Support new simulation component: extragalactic/clusters

Support simulate the radio emission from clusters of galaxies.
Currently only the radio halos is considered, while the radio relics
need more investigations.

Also, this simulation requires a cluster catalog derived from the Hubble
Volume Project simulation.

NOTE: not tested at the moment
