I would also stick with interface option since it makes it easier to deal
with backwards compatibility. We can just add another interface and keep the
code path for the old interface, without polluting the `MetricReporter`
interface.

> By default Flink uses a period to separate scope components. This is however
> not the default for all reporters, which results in either users having to
> override the delimiter manually or reporters working around this issue.
> It would be cleaner if the would let reporters define their own default
> delimiter.
