feat(vm_extensions): add boot validation tests for Azure Security Linux Agent and Azure Monitor Linux Agent

[Jayprakash gupta (Jaype-e)]

Summary

Adds dedicated boot-validation test suites for two VM extensions, following the existing VmExtensionTestBase onboarding pattern (same as CustomScript / AKS Linux Billing):

• Azure Security Linux Agent — Microsoft.Azure.Security.Monitoring.AzureSecurityLinuxAgent
• Azure Monitor Linux Agent — Microsoft.Azure.Monitor.AzureMonitorLinuxAgent

Each suite installs the extension with empty settings, asserts provisioning succeeds, verifies the installed version (when a full Major.Minor.Patch is requested), confirms the VM stays reachable over SSH, then removes the extension. All logic is delegated to the shared _boot_validation helper — no duplicated flow.

No boot-validation coverage existed for either extension. The existing AzureMonitorAgentLinux suite only provides a separate functional verify_azuremonitoragent_linux test and is left untouched.

Validation

Both files pass: py_compile, flake8, isort, black, and strict mypy, and register correctly with the LISA test selector (area=vm_extension, category=functional, priority=5, maturity=preview).

Version is read from the extension_version (or the per-suite {key}_version) runbook variable; it is required (no default fallback), matching the boot-validation contract.

Test guidance

Key Test Cases:

Pull request overview

Adds two new VM extension boot-validation test suites under runtime_extensions/, following the existing VmExtensionTestBase pattern, to cover basic install/provision/version/SSH-reachability/uninstall validation for Azure Security Linux Agent and Azure Monitor Linux Agent.

Changes:

• Introduces AzureSecurityLinuxAgentTests boot-validation suite for Microsoft.Azure.Security.Monitoring.AzureSecurityLinuxAgent.
• Introduces AzureMonitorLinuxAgentTests boot-validation suite for Microsoft.Azure.Monitor.AzureMonitorLinuxAgent.

• simple_requirement() excludes Windows by default only when neither supported_os nor unsupported_os is provided (see lisa/testsuite.py:446-449). By setting unsupported_os=[BSD] here, Windows becomes eligible for this suite, but this extension is Linux-only and will likely fail when scheduled on Windows images. Exclude Windows explicitly (or set supported_os=[Linux]).
