@NazIrizarry Thanks for the contribution! I can certainly understand how
this is a useful feature to have. The only concern that I have is that I don't
believe that "Run Once" fits as a Scheduling Strategy. Instead, I think the
user should have the ability to right-click on a Processor and click "Run Once"
and the Processor would then immediately run, regardless of what the scheduling
strategy is (though if configured to run on Primary Node only, it should still
only run on Primary Node).
Thanks

>
> A run once scheduling option allows a Processor to run once and then
> automatically stop. This is convenient when developing and debugging flows,
> or when building "visual scripts" for ad-hoc process integration or iterative
> analytics. Individual processors set to `Run once' can be selected on the
> canvas with a shift-click. Then clicking `Start' on the Operate Palette will
> start those processors which will run once and stop. Then one can modify
> processing parameters and repeat. Interactive analytics in particular
> benefit from this scheduling mode as they often require human review of
> results at the end of a flow followed by adjustment of flow parameters before
> running the next analytic flow.
