Pull request overview

This PR adds a new integration test that verifies the combination of DHCP, NTP, and DNS functionality. Specifically, it tests that statically configured DNS and NTP servers are preserved (not lost) when a client also receives DNS and NTP server information from a DHCP server. The test validates that both the static and DHCP-provided servers coexist in the system's operational state.

Changes:

• Added a new use case test for DHCP + NTP + DNS combination
• Created topology files and test documentation
• Updated test suite configuration to include the new test
