get_node_extrainfo.sh recipe doesn't return any data when using LEVEL '0'

Hi @QuaCKeReD

Thanks for developing the script to extract detailed Node info. However, we've been trying to get the nodes info at controller level and running into issues, as it returns an empty data set.

https://github.com/Appdynamics/api-commandline-tool/blob/master/recipes/get_node_extrainfo.sh

./get_node_extrainfo.sh -E saas-nonprod -L 1 ENVIRONMENT: saas-nonprod | LEVEL: 1 | APP_ID: | SOURCE: 0 | DEST: 0 appId,appName,nodeId,nodeName,tierName,machineName,machineOSType,machineAgentVersion,appAgentVersion,agentType,jvmVersion,appServerRestartDate

Running the command with application Id returns expected data

./get_node_extrainfo.sh -E saas-prod -A 4087 ENVIRONMENT: saas-prod | LEVEL: 0 | APP_ID: 4087 | SOURCE: 0 | DEST: 0 appId,appName,nodeId,nodeName,tierName,machineName,machineOSType,machineAgentVersion,appAgentVersion,agentType,jvmVersion,appServerRestartDate 4087,**-***,800829,10.10.119.11,JMS,***-***-***,Windows,false,Server Agent #20.10.0.31173 v20.10.0 GA compatible with 4.4.1.0 r29ff7e90931b7171bbfd8336067028701025517a release/20.10.0,APP_AGENT,"Java HotSpot(TM) 64-Bit Server VM 1.7.0_71 Oracle Corporation",1638685355644

Masked some information for security purposes in the above output.

从 recipes/get_node_extrainfo.sh 开始，使用文档中说明的 -E 和 -L 选项重现空输出，并将其与正常工作的 -A 4087 调用进行比较。跟踪 LEVEL 0 的处理方式，并验证 recipe 在保留现有 CSV 输出格式的同时，能够在 controller 级别返回 node 数据。
