api: remove unused equals/hashCode from TemplateOVFPropertyResponse

TemplateOVFPropertyResponse is not referenced anywhere outside its own class: nothing keys it in a set or map or compares instances, so its equals()/hashCode() pair has no callers. hashCode() also dereferenced key without a null guard. Remove both methods rather than harden dead code, which also drops the NPE path.
