[consideRatio]

For epic #4365.

• Use the google cloud web console instead of terraform as this is a one time cloud infra setup
• Create a new GCP project under the 2i2c.org GCP organization
  name: binderhub-event-logs, put under org-wide folder in the 2i2c.org GCP organization
• Enable Cloud Logging in the project
  It was enabled by default.
• Create a dedicated log bucket under "Logs Storage" with a rentention period of 731 days (two years)
  name: binderhub-event-logs
• Create a GCP service account (SA)
• Grant the SA the role Logs Bucket Writer (expected to be the minimal permissions needed)
