add hostname attribute for overwriting hostRequires
Created by: wizardofoz123
This is kpet change necessary to implement FASTMOVING-740.
This patch adds hostname attribute into host/host type.
This allows kpet-db jinja template to insert element insteadof any normal hostRequires. This change is independent from kpet-db, but in order to work, kpet-db needs tiny either/or change in template.
