Kirill Ilin 63f9926192 feat(keycloak): allow overriding the database host/port/properties (#2907)
## What this PR does

Makes the Keycloak database connection target configurable, so the
connection
can be routed through an external endpoint (for example a connection
proxy such
as PgBouncer or another pgwire proxy) without forking the chart:

- `db.host` / `db.port` — override the host/port otherwise read from the
  `keycloak-db-app` secret.
- `db.urlProperties` — sets `KC_DB_URL_PROPERTIES` (previously never
set), e.g.

`?sslmode=verify-full&prepareThreshold=0&sslrootcert=/etc/keycloak-db-ca/ca.crt`.
- `extraVolumes` / `extraVolumeMounts` — mount additional volumes on the
  Keycloak container (e.g. a CA for `sslrootcert`).

All new values default to empty, so the rendered StatefulSet is
byte-for-byte
unchanged for existing installs (verified with `helm template`).
Credentials
and database name are still taken from the `keycloak-db-app` secret.

### Release note

```release-note
feat(keycloak): allow overriding the database host/port/URL properties (db.host, db.port, db.urlProperties) and add extraVolumes/extraVolumeMounts, so the DB connection can be routed through an external proxy
```
