add hostname attribute for overwriting hostRequires
Created by: wizardofoz123
This is kpet change necessary to implement FASTMOVING-740.
This patch adds hreq_forced attribute into host. This attribute contains the first string from yaml that contains 'hostRequires force' substring; cases are scanned first, then suites.
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 hostRequires files have to be deleted and XML snippets moved to yaml.
