verify_dns_name_resolution_after_upgrade - mark node dirty after OS u…

[SRIKKANTH]

…pdate

After OS upgrade sometimes kernel version may change. When LISA is used to validate a VM image with specific kernel version, changing the kernel will result in running tests with undesired kernel which should be avoided. Marking the node dirty after OS update to avoid such issues.

Pull request overview

This PR updates the core DNS test case that performs an OS upgrade so the test environment is marked as “dirty” after the upgrade, preventing subsequent test cases from reusing a potentially kernel-changed node.

Changes:

• Mark the test node dirty in verify_dns_name_resolution_after_upgrade to avoid environment reuse after OS upgrade.
