public CollectionName(string projectId, string locationId, string collectionId)
Constructs a new instance of a CollectionName class from the component parts of pattern
projects/{project}/locations/{location}/collections/{collection}
If true will successfully store an unparseable resource name into the UnparsedResource
property; otherwise will throw an ArgumentException if an unparseable resource name is
specified.
