Create a "universal" load generator about cloud-ops-sandbox HOT 5 OPEN

@minherz During the POC we created the universal log generator for logs using Python, will be happy to share source code in case you need it.

Hi @minherz, I can work on this. Just wondering: what is wrong with the load generator included with the Online Boutique? It is able to send GET and POST requests to multiple points with complex scenarios, as configured in https://github.com/GoogleCloudPlatform/microservices-demo/blob/main/src/loadgenerator/locustfile.py:

Could you provide a specific example of a feature that is currently missing?

There is nothing wrong with LG in OB. the goal of this issue is to provide an alternative LG as a part of COS.
When I tried to use LG that comes with OB I found out that it does not expose UI interface. According to what I see in the code it runs a preset configuration of the load that cannot be changed. While it is good enough to show o11y data, it is not sufficient for simulating scenarios that are exposed under heavy load.

Got it. I agree the LG in OB does not seem to support custom load shapes for example. But then I wonder how to make a "universal" load generator with a large (infinite?) number of scenarios with a reasonable amount of time and energy on our side. Would it make more sense to let users spawn their own Locust container on their local machines, with their custom tasks? And document the whole thing with an example on our side.

This sounds like a great idea! I am unsure if we want to document the Locust load generator but we certainly can provide guidelines and to use Online Boutique as an example.
