Ensure only one instance of a pipeline can run at the same time
Sometimes you want to ensure that only a single instance of a pipeline can run at a time. This is important if the stages of a pipeline are interrelated. For example the first stage may set up an environment that is used by the next stage in the pipeline.
If a pipeline is locked then Go will not allow any other instance of that pipeline to be scheduled until the currently running one has been completed.
