## Description:

Currently, the helm chart of PMM is setting a password for Grafana via a Secret. Please see below code.

> <https://github.com/percona/percona-helm-charts/blob/b26b54ecec3f629f41f88e4fa3323fb2910c0ec4/charts/pmm/templates/statefulset.yaml#L76-L81>

Once the PMM Server get started successfully, I changed the password in a Secret for Grafana, and I restarted the PMM Server Pod to apply it.

But seems the new password was not applied to Grafana as it still succeeded to login to Grafana with old password. ☹

## Steps to Reproduce:

1. Install the PMM Chart with some password.
2. Once the PMM Server get started, change the Secret that contains a password with new password.
3. Restart the PMM Server Pod to make it get a new password.
4. Check if you can access the Grafana with new password.

## Version:

v2.40.1

## Logs:

There is no specific logs but you can see the issue with the above reproduction steps.

## Expected Result:

The PMM Server POD should run with new password.

## Actual Result:

The PMM Server POD is still using the old password so that I cannot access it with new password.

## Additional Information:

Seems there is a related issue at the Grafana side: [Changed Environment Variables do not get picked up in Grafana even though the `env` command has the updated values · Issue #49055 · grafana/grafana · GitHub](https://github.com/grafana/grafana/issues/49055)
