The `import` operator is a remote event sink for a pipeline that imports events into VAST. This current implementation is very basic, and simply forwards events to the existing `importer` singleton component in the VAST node. In the future, we should change the `import` operator to directly create passive partitions, and to send then to the catalog directly, which will enable better fault tolerance. That, however, is a change we can make in the future, as VAST's internal APIs are not well suited for that at the current point in time. To make testing easier, this also implements a `repeat` operator that repeats an input (either bytes or events) a given number of times.
Sometimes with metrics you only care about the accumulated total, but want to see that updating live. This is what `measure --cumulative` gives you: a running total of events or bytes going into the operator.
