Support GCP IAM authentication for Redis

[Momotoculteur]

Describe the problem

Allow the Weblate Helm chart to connect to Google Cloud Memorystore Redis using IAM authentication instead of static passwords. We could use a traditional username/password account which is not the best way to achieve that from google, we should use a service account for that (which has not password for this type of account)

Solution brainstorm

Currently, the chart only supports standard Redis passwords. In GCP, Memorystore can now support IAM-based authentication for Redis, and the Python library google-cloud-iam
allows generating short-lived access tokens to connect. Here an exemple

Hello @Momotoculteur,

It seems to me that this is not directly related to the Weblate Helm chart. Your suggestion appears to be more related to the Weblate application itself rather than the Helm chart. The application would need to implement a dynamic credential provider (not sure if it exists or not).

Or am I missing something?
