chore(ci): add static config for deploy nested cluster and configure ci for nightly e2e tests

[universal-itengineer]

Description

This PR adds support for automated E2E testing of the Virtualization module in nested clusters for nightly tests. A complete infrastructure is implemented for deploying a static Deckhouse cluster with support for various storage types (Ceph and Replicated), configuring the Virtualization module, and running E2E tests.

Key Changes:

• New reusable workflow (.github/workflows/e2e-reusable-pipeline.yml) for E2E testing with parameterization support
• Updated matrix workflow (.github/workflows/e2e-matrix.yml) with support for running tests for different storage types
• Static cluster infrastructure (test/dvp-static-cluster/) including:
  • Helm charts for cluster and infrastructure configuration
  • Scripts for kubeconfig generation and Deckhouse queue management
  • Storage configurations (Ceph and SDS Replicated)
• CI/CD improvements:
  • Automatic generation and configuration of kubeconfig for nested cluster
  • Storage setup (Ceph/RBD and SDS Replicated)
  • Virtualization module configuration with support for various storage classes
• Various fixes in templates and configurations

Why do we need it, and what problem does it solve?

What is the expected result?

Checklist

• The code is covered by unit tests.
• e2e tests passed.
• Documentation updated according to the changes.
• Changes were tested in the Kubernetes cluster manually.
