[libvirt] [PATCH v3 11/16] util: Introduce virObjectLookupHashFind



This API will use the virHashLookup in order to find the object in
the requested hash table (via @useUUID) by the specified @key. It is
up to the caller to know which table (UUID or Name) to find the data
by @key and handle the error or NULL return.
