'agnhost' image uses hardcoded 'cluster.local' value for DNS domain.
It leads to failure of a bunch of HPA tests when test cluster is
configured to use custom DNS domain and there is no alias for
default 'cluster.local' one.
So, fix it by reusing it's own function for reading DNS domain suffixes.

Refactors the functions used in agnhost into different modules,
based on their functionality, leaving only the main in the base
folder.
Future commits will add several functionalities to agnhost, so
this change will be necessary to keep it clean.
