> Using an example to explain:
> 1) Admin specify host1 has label=x
> 2) node=host1:123 registered
> 3) Get node-to-label mapping, return host1/host1:123
> 4) node=host1:123 unregistered
> 5) Get node-to-label mapping, still returns host1:123
> Probably we should remove host1:123 when it becomes deactivated and no directly label assigned to it (directly assign means admin specify host1:123 has x instead of host1 has 123).
