Testing Plan

Change INI value, run SDL core, ensure Core read new INI value
Unit Tests and ATF tests

Summary

Refactor INI parsing to reduce the number of times the ini file is opened. This goal is achieved through an update to Profile::UpdateValues:

1. INI file is opened
2. all values from the file are read into a smart_object
3. INI files is closed
4. Member variables are assigned from values in smart_object

Changelog

Enhancements

CMake

• transport_manager now requires smart_object include
• config_profile now depends on smart_object
• config_profile_test now depends on smart_object

Tasks Remaining:
