Fixes#7467
The -mserver argument line in volume-statefulset.yaml was missing a
trailing backslash, which prevented extraArgs from being passed to
the weed volume process.
Also:
- Extracted master server list generation logic into shared helper
templates in _helpers.tpl for better maintainability
- Updated all occurrences of deprecated -mserver flag to -master
across docker-compose files, test files, and documentation
Fix the templates to read scheme from httpGet.scheme instead of the
probe level, matching the structure defined in values.yaml.
This ensures that changing *.livenessProbe.httpGet.scheme or
*.readinessProbe.httpGet.scheme in values.yaml now correctly affects
the rendered manifests.
Affected components: master, filer, volume, s3, all-in-one
Fixes#7615
