This commit migrates the SRP auto-start test from the Python-based thread-cert test suite to the Nexus C++ test framework. The new Nexus test replicates the logic of the original Python test: - Forms a network with four router nodes. - Verifies SRP client auto-start upon server discovery in netdata. - Tests selection priority between multiple unicast and anycast SRP servers. - Verifies selection based on anycast sequence numbers. - Tests selection of specific unicast addresses published in Service Data. - Confirms automatic failover and client stop/restart. The original Python test file is removed as it is now covered by the Nexus test suite.
