ci: make integration test vm name more unique

[KauzClay]

add the os_line and go to seconds when putting the timestamp. Sometimes multiple jobs have been running in the same minute and got the same test vm name.

the task already defines os_line as a param:

bosh-windows-stemcell-builder/ci/tasks/setup-integration-test-vm/task.yml

Line 16 in 995bb08

OS_LINE:

Walkthrough

The integration test VM clone name now includes OS_LINE and a UTC timestamp with seconds precision.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to 995bb

Clone names now include the OS line and second-level time. The configured pipeline jobs prevent the identified same-second collision, so no actionable merge-blocking risk remains.

Security Architecture Review

Security architecture risk: ⚪ Minimal · up to 995bb

The change makes integration VM names more specific without changing credentials, configured infrastructure targets or cleanup selection. The configured callers supply a fixed OS value, and consumers use the saved name rather than parsing its format. No material security risk was found introduced or worsened by this change.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — The configured privileged operations remain integration VM creation, customization, power-on and deletion in the existing vCenter folder. The naming change does not modify the supplied credentials or infrastructure targets; source configuration does not establish the credentials' maximum permissions.

Trust Boundaries and Controls

• inferred — For the configured callers, adding a fixed OS value to quoted VM-name arguments does not introduce an attacker-controlled path component or a new shell execution path. Cleanup continues selecting the persisted identity rather than discovering targets by prefix.

Resilience and Maintainability Implications

• observed — Failure handling predates this PR: setup exits on errors and has bounded polling loops, while cleanup skips deletion when the artifact directory is absent and tolerates destroy failures. The persisted cleanup target remains unchanged across later setup failures, but artifact availability after runtime interruption is not established by repository source.
