QuiesceObjector constructor
Constructs a new QuiesceObjector based on isActive.
If timeout is provided, then if there is no activity before it completes, then it will flag an error.
If dropDelay is provided, then there will be a delay on dropping an objection until it completes.

QuiesceObjector(
this.isActive, {
required Component parent,
String name = 'quiesceObjector',
this.timeout,
this.dropDelay,
}) : super(name, parent);
