installer node can be any nodes as long as it can ssh to Trafodion nodes, it also can be one of the Trafodion nodes

How to use:

• Two ways:
• Simply invoke ./db_install.py to start the installation in guided mode
• Copy configs/db_config_default.ini file to your_db_config and modify it, then invoke ./db_config.py --config-file your_db_config to start installation in config mode
