hydra-automigrate is logging database DSN with password

[juusujanar]

Describe the bug

Hydra auto-migrate init container in Kubernetes logs multiple lines, which include the full DSN (which includes the database password). Info log level lines are also there, which hide database user and password with asterisks.

To Reproduce

Steps to reproduce the behavior:

1. Enable autoMigrate in helm chart
2. Deploy the chart.
3. Check initContainer logs.

Expected behavior

Database password does not get logged.

Environment

• Docker image oryd/hydra:v1.0 with image ID oryd/hydra@sha256:c60c647f6f34502ec6807a8423fb9cde0128abed3128c3d203750b68bb2ef81f (Docker Hub gives timestamp 3 days ago)
• Tested in a Google Kubernetes Engine cluster.

Additional context

Logs from the init container pod.
