Breaking changes

• [REMOVAL] Remove build option WITH_DEPRECATED_SDK_FACTORY
  #2717

  • As announced in opentelemetry-cpp previous release 1.16.0,
    CMake option WITH_DEPRECATED_SDK_FACTORY was temporary,
    and to be removed by the next release.

  • This option is now removed.

  • Code configuring the SDK must be adjusted, as previously described:

    • [API/SDK] Provider cleanup
      #2664

    • Before this fix:

      • SDK factory methods such as:

        • opentelemetry::sdk::trace::TracerProviderFactory::Create()
        • opentelemetry::sdk::metrics::MeterProviderFactory::Create()
        • opentelemetry::sdk::logs::LoggerProviderFactory::Create()
        • opentelemetry::sdk::logs::EventLoggerProviderFactory::Create()

        returned an API object (opentelemetry::trace::TracerProvider)
        to the caller.

    • After this fix, these methods return an SDK level object
      (opentelemetry::sdk::trace::TracerProvider) to the caller.

    • Returning an SDK object is necessary for the application to
      cleanup and invoke SDK level methods, such as ForceFlush(),
      on a provider.

    • The application code that configures the SDK, by calling
      the various provider factories, may need adjustment.

    • All the examples have been updated, and in particular no
      longer perform static_cast do convert an API object to an SDK object.
      Please refer to examples for guidance on how to adjust.
