Flask example

This example demonstrates the integration with the Flask web-framework.

Running the example

Start an instance of SBA (Spring Boot Admin):

docker run --rm -p 8080:8080 --add-host=host.docker.internal:host-gateway michayaak/spring-boot-admin:2.2.3-1

Once Spring Boot Admin is running, you can run the examples as follow:

cd examples/Flask
poetry install
poetry run python -m flask_example_app

Note that when Flask debugging is enabled, Pyctuator and Flask are initialized twice because Flask reloads the script. This causes Pyctuator to register twice thus the startup time alternates between the time these instances started.
```
app.run(port=5000, host="0.0.0.0", debug=True)
```
