Consolidate more wildcarded lifecycle domain testdata XMLs

Specifically domain_info.xml, domain_delete.xml, and domain_create_response.xml.

As of this CL, all domain-related commands are standardized on the parameter
"DOMAIN" for the domain name. No more ambiguous "NAME", which could be confused
with a host name.

This finishes the domain_create_response consolidation work from []
