PluginManagerCMD in JMeterInstaller task fails due to missing proxy settings

[kevinrossnl]

We use onprem buildservers that require proxy configuration settings to download from the internet.

During the JMeterInstaller it fails on the PluginManagerCMD which is unable to download the plugins:
[command]C:\Windows\system32\cmd.exe /D /S /C "D:\azagent-p\A1\_work\_temp\36be6146-6a29-446f-8f86-595d7583904c/apache-jmeter-5.4.2/bin/PluginsManagerCMD.bat install "jpgc-casutg,jpgc-dummy,jpgc-ffw,jpgc-fifo,jpgc-functions,jpgc-json,jpgc-perfmon,jpgc-prmctl,jpgc-tst""
The earlier downloads that you do work fine. I believe you should add an option to pass JVM_ARGS with proxy settings (host, port, password, user, no_proxy) towards the PluginManagerCMD. More info Plugin Manager behind Proxy
