IoTDB Runtime information collection tools

# Tools

Supply two scripts to collect the information of an IoTDB process. This could be used by the operations people in the production environment.

* tools/iotdb-runtime-information-collection.sh
* tools/iotdb-runtime-information-collection.bat

# Collect information:

## Thread status (To detect deadlock)

* use jps to get the IoTDB process id -> pid
* collect the thread status twice (interval 1s)
* jstack -l pid > jstack_1.log
* jstack -l pid > jstack_2.log

从 tools 目录开始，检查所请求的 tools/iotdb-runtime-information-collection.sh 和 tools/iotdb-runtime-information-collection.bat 入口点。检查 jps 如何识别 IoTDB 进程，然后以一秒的间隔使用两次 jstack，生成 jstack_1.log 和 jstack_2.log。当两个脚本都收集到生产运维所需的指定线程状态信息时，即表示完成。
