Add an output property to StartLiveData pointing to the ongoing MonitorLiveData instance

[Russell Taylor]

I have a need to be able to stop the live data reading in my Step Scan GUI (and, I expect, in other tools in the future). Therefore, I'm going to add an output property (of type AlgorithmProperty) to StartLiveData that passes back the MonitorLiveData that continues once StartLiveData is done. I can then use this to cancel live reading when required.

Re #6768. Add an output property 'MonitorLiveData' to StartLiveData

that gives back a reference to the algorithm that continues to read live data after StartLiveData completes. Can be used to cancel live data reading programatically.

Re #6768. Expose AlgorithmProperty to python.

This is needed to avoid an error if you try to capture the return value from StartLiveData in python, now that this algorithm has an output property of this type. You can't really do much with it right now, but if needed later we could expose the IAlgorithm::cancel method.

Tester:

• Note the new property and that it's used in the unit test
• Check that StartLiveData can be run from the GUI (choose the 'FakeEventDataListener')
• Check it from python with the following commands:

  x = StartLiveData('FakeEventDataListener',OutputWorkspace='ws',AccumulationWorkspace='')
  print x
  

  Note that x is a tuple, where the last element is of type IAlgorithm. This is the new output property.
