Gather GUIDs from applications only with v4.0.0

首先复现 cf log-meta --noise --guid --sort-by=rate --source-type=application 以及不带 --source-type 的较新命令，然后检查用于验证 --guid 和 --source-type 的 CLI 入口点。比较 v3.1.0 与最新版本的行为；当 application GUID 输出能够可靠地单独提取，或受支持的替代方案已记录时，即可完成。

In order to get a list of the noisy neighbour applications up until now (up until the latest 4.0.0 release ) we were using v3.1.0 and the following command to get the GUIDs of the applications together with the log stats:

cf log-meta --noise --guid --sort-by=rate --source-type=application

After we get the guids we run another CF API call to get the organization and space where the app is running:
cf curl /v3/apps?guids=GUID[i]&include=space,space.organization and the end we show everything as a table.

Now we've installed the latest version of the log-cache cli plugin and we've got an error that the --guid switch can only be used with --source-type=platform. Therefore we've tested with:

cf log-meta --noise --sort-by=rate  --guid

and in the output we've found guids and names of the CF's system components like:

Are the GUIDs only from running applications? Can we simply run the output through GUID validator to filter out the system components and leave the application guids only?

Is there some other way to get only the guids of the applications?
