[NouemanKHAL]

What does this PR do?

• Add support for running E2E tests on VMs.

• Updates the AgentInterface to pass the entire Application object which includes logging functionalities from the Terminal base class and access to ddev config via the self.config member.

• Uses the E2E_METADATA as an interface to customize the VM via the following properties:

VM Configuration

• vagrant_box: Specifies the Vagrant box image (defaults to "net9/ubuntu-24.04-arm64")
• vagrant_guest_os: Determines OS type ("linux" or "windows" not supported yet) for path formatting and commands
• vagrant_synced_folders: List of additional folders to sync between host and VM

Agent Configuration

• env: Dictionary of environment variables to export in the VM
• dd_hostname: Custom hostname for the Agent
• dd_apm_enabled: Enable/disable APM (defaults to "false")
• dd_telemetry_enabled: Enable/disable telemetry (defaults to "true")
• dd_expvar_port: Port for expvar endpoint (defaults to "5000")
• proxy: HTTP/HTTPS proxy configuration

Lifecycle Commands

• start_commands: List of shell commands to run during VM startup
• post_install_commands: Commands to run after local package installation
• stop_commands: Commands to execute before VM shutdown

Permission Management

• vagrant_sudoers_config: Custom sudoers rules for dd-agent user
• vagrant_logs_require_sudo: Whether sudo is needed to read agent logs (defaults to true)
• vagrant_command_needs_sudo: Global sudo requirement flag

Provisioning Control

• vagrant_provision: Flag to force provisioning on next vagrant up
• vagrant_provision_on_reload: Whether to reprovision on VM reload (defaults to true)

Windows-specific

• vagrant_windows_agent_service_name: Service name for Windows Agent (defaults to "DatadogAgent")

Motivation

Provide better E2E testing for host based integrations.

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• Add the qa/skip-qa label if the PR doesn't need to be tested during QA.
• If you need to backport this PR to another branch, you can add the backport/<branch-name> label to the PR and it will automatically open a backport PR once this one is merged
