Create a method to start a run

[hansende]

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

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

logs: optional

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

The Method "start" adds the node_type "start" to the request

Test:

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

When successful there will be a started flow, which can be watched in the related public dashboard:
