------------------------------------------------------------
Thanks [~rchiang] for reiterating the design goal of {{DiskValidator}}. Agree
to separate {{DiskValidator}} and {{DiskValidatorService}} interfaces. BTW, do
we want to support users' own disk validator plugins in current design as
[~rkanter] mentioned? I don't think it is a good idea to support that since
they can do anything.
I prefer to keep {{DiskValidator}} simple first. If we want a {{Service}}, we
can create a {{Service}} to invoke {{DiskValidator}} just like what
{{LocalDirsHandlerService}} does.
