Allow Python to list and cancel running algorithms

[Nick Draper]

It should be possible to list running algorithms (and access input properties).

With an algorithm handle (or alg proxy handle) it should be possible to call .cancel() to stop the algorithm.

Create an example script that shows cancellation of MonitorLiveData using a fake data generator and the following scenarios:

1. Cancel after a period of time
2. Cancel after a certain number of events
3. Cancel by listing the running algorithms, selecting and cancelling (in another script).

Branch: feature/8971_cancel_algs_from_script

Tester: I have attached 3 scripts as required. The first demonstrates cancelling the MonitorLiveData algorithm after a certain time and after a certain number of events have been captured. The final 2 are meant to be used together:

• test_live_cancel_different_script1.py - Starts a live data capture algorithm
• test_live_cancel_different_script2.py - Cancels the newest instance of a running MonitorLiveData algorithm
