Combined BeforeBuild_setNodeID.sh, build_container.sh, and run_container.sh into build-n-run.sh.
build-n-run.sh takes arguments to setup NodeID, external volume location, and debug shell for container.
Renamed initialize_db to initialize_zabbix_db.
Rename zabbix_server.conf to zabbix_server.conf.template.
container_init will setup zabbix database automatically if it does not exits.
