fix: k8s:resource replaces template variables in provided fragments, k8s:helm doesn't.

[manusa]

Description

Fixes: #327

• Moved logic from ResourceMojo to separate service
• Fixed Resource generation, template placeholders are replaced only in aggregated YAML file (kubernetes.yml)
  not in individual resource files.
• Placeholder/variable replacement can be turned off (jkube.interpolateTemplateParameters)
• Fixed Helm chart generation, template placeholders are NOT replaced.
  Provided support for Parameters with no default value (values.yml) will only contain those which have a default.
  The rest of parameters can be specified with --set option
• Added integration test to verify behavior for resource and helm YAML generation.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• Feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change (breaks current behavior because current behavior is buggy and inaccurate to spec)
• Chore (non-breaking change which doesn't affect codebase;
  test, version modification, documentation, etc.)
