Add config flags to control zone migration test execution

Add configuration checks to conditionally skip zone migration
tests that require specific setup or code. This allows
better control over which tests run in different CI environments.

Changes:
- Add run_zone_migration_extra_tests flag check to skip
  zone migration for instances without dst_node tests when disabled
- Add run_zone_migration_storage_tests flag check to skip
  storage-related zone migration tests when disabled
