Create a python method to stop a run

[hansende]

Create a Python Method in the existing FlowMetr Python class to stop a run for a flow, which can be called like:

flow1.stop(node_id="stop-trigger", run_id="my first run", logs="just started")

logs: optional

The method stop will create a http get request to the flowmetr backend like:

the stop method adds the node_type "stop" to this request

Test:

Can be tested locally with FlowMetr started through docker
compose or with a flow in Flowmetr Cloud.

When successful there a previously started flow is stopped after calling the method, which can be watched in the related public dashboard:
