Cloud Run endpoint demo auth token generator

Given you already have a Cloud Run instance with Authenticated Access running, follow the steps below:

1. Create service account with per-service permissions (Service Identity, Authenticating Developers)
2. Download API key JSON (Create and manage keys)
3. Create python environment and install dependencies

python -m venv env
source ./env/bin/activate
pip install -r requirements.txt

4. Run the token generator script

python run.py --url=[FULL_API_ENDPOINT] --credentials=[CREDENTIALS_JSON_FILE_PATH]

where FULL_API_ENDPOINT is the full path, including the endpoint (without the query params), i.e. https://my-service-jfkie.a.run.app/my-service-endpoint, and CREDENTIALS_JSON_FILE_PATH is a full path to the file downloaded in step 2 (i.e. /Users/jon.do/Downloads/my-credentials.json).
