A common object API wrapper to use the virHashSearch API to search the
specified LookupHash for specific data defined in the @opaque parameter.
Once data is found, the search would end and the LookupKeys object that
is represented is returned locked with it's reference count incremented.
It is up to the caller to unlock and lower the refcnt once done with the
object and of course handle a NULL return indicating no object found.
