config.c: Added configuration parameter processing for read_ses_variables_from_slaves and for write_ses_variables_to_all . The values are read from config file, qualified and stored to service. Values are loaded when instance is created. This is limitation in current implementation and will change so that configuration is dynamically changeable.
