Pull Request Overview

This PR aims to fix conformance test issues by reducing the initialization synchronization delay and enhancing the SSL merging logic in the ADC translator. Key changes include:

• Reducing the InitSyncDelay from 30 minutes to 1 minute within the test suite.
• Adding debug logging and implementing a merge function for SSL objects with identical IDs.

• Consider adding a comment to explain the rationale behind reducing InitSyncDelay from 30 minutes to 1 minute so that future maintainers understand this test-specific configuration.

Pull Request Overview

This PR fixes an issue where duplicate SSL objects were not merged during gateway translation. Key changes include:

• Reducing the test suite's sync delay from 30 minutes to 1 minute.
• Adding a new mergeSSLWithSameID function to consolidate duplicate SSL objects.
• Introducing debug logging for generated SSL IDs.

• Consider adding unit tests for the mergeSSLWithSameID function to validate its behavior with various duplicate SSL scenarios.

mergedSSL := make([]*adctypes.SSL, 0, len(sslMap))

[nitpick] Consider revising the function comment to 'Merge SSL objects with identical IDs' for improved clarity.
