Add qBittorrent Chart

[Matthew-Beckett]

This pull request introduces a new Helm chart for deploying qBittorrent, leveraging the shared arr-common chart components for consistency and maintainability. It includes all the necessary chart files, default configuration values, documentation, and a comprehensive set of Helm unit tests to ensure correct rendering of Kubernetes resources.

Key changes:

New Helm Chart Definition and Configuration:

• Added a new qbittorrent Helm chart with metadata, dependencies (on arr-common), maintainers, and application versioning in Chart.yaml.
• Provided default configuration values in values.yaml, including image details, environment variables, service configuration, persistence, probes, resources, and optional integrations for metrics and VPN (gluetun).

Documentation:

• Added a detailed README.md documenting chart usage, configuration options, maintainers, and dependencies.

Template Implementation (using arr-common):

• Implemented chart templates for deployment, ingress, PVC, service, and servicemonitor by including corresponding arr-common templates for consistency:
  • deployment.yaml
  • ingress.yaml
  • pvc.yaml
  • service.yaml
  • servicemonitor.yaml

Testing:

• Added Helm unit tests for all major templates to verify correct resource rendering and configuration under various scenarios:
  • Deployment tests (deployment_test.yaml)
  • Ingress tests (ingress_test.yaml)
  • PVC tests (pvc_test.yaml)
  • Service tests (service_test.yaml)
  • ServiceMonitor tests (servicemonitor_test.yaml)

Ownership:

• Added a CODEOWNERS file to specify repository ownership for the chart.
