Statping chart stores database password in ConfigMap, not in secret

[florian-besser]

As part of applying this helm chart the configMap statping is created. This configMap may contain:

apiVersion: v1
data:
  DB_CONN: postgres
  DB_DATABASE: statping
  DB_HOST: CENSORED
  DB_PASS: CENSORED
  DB_PORT: "5432"
  DB_USER: statping
  DEBUG: "1"
  DISABLE_COLORS: "true"
  PORT: "8080"
  POSTGRES_SSLMODE: require
  READ_ONLY: "false"
kind: ConfigMap
metadata:
  annotations:
    meta.helm.sh/release-name: statping
    meta.helm.sh/release-namespace: alm
  creationTimestamp: "2024-01-19T04:10:45Z"
  labels:
    app.kubernetes.io/managed-by: Helm
  name: statping
  namespace: alm
  resourceVersion: "202811663"
  uid: 591735bc-3fa7-47f0-95f6-72462c848995

(fetched using kubectl get cm -n alm statping -o yaml

I have censored the hostname and password in the output.

Passwords and other sensitive information should be stored in secrets, as there may be people running around the cluster with privileges to read ConfigMaps (for easy maintenance, changing configs) but they can't read secrets (to keep the secrets actually secret!)

I can provide a PR if this is a desirable change.
