Add option to ignore all proxies

[jakegt1]

I cannot get environment variable set proxies to not apply to vscode java in any way. I do not want to set a proxy, so it would be nice to have an option to force it to ignore all system proxies.

Environment

• Operating System: CentOS 7
• JDK version: 11
• Visual Studio Code version: 1.56.2
• Java extension version: 0.79.1

Steps To Reproduce

1. Set http_proxy in bashrc
2. Vscode java doesn't work because it tries to route through the proxy

Current Result

!ENTRY org.eclipse.buildship.core 2 3 2021-05-14 15:16:23.920
!MESSAGE Synchronize project $SOME_PROJECT failed due to an error connecting to the Gradle build.
!STACK 0
org.gradle.tooling.GradleConnectionException: Could not install Gradle distribution from '$INTERNAL_URL/gradle/7.0.2-bin/gradle-7.0.2-bin.zip'.

Expected Result

Add feature to ignore system proxies so as nothing i do with this plugin is external

Additional Informations

I've had forms of this problem for absolutely ages. I've tried to set a proxy using system properties, which doesn't seem to work. The only way i can get this to work is by changing bashrc to not set proxies at all, restarting vscode and then running the plugin.
If there was an option to force disabling of all proxies, that would be great as then i don't have to worry about trying to configure a proxy or having to deal with the proxy working anyway.

The other option would be to have the plugin respect the no_proxy environment variable which it does not seem to do.

@jakegt1 could you try to add the following setting:

"java.jdt.ls.vmargs": "-Dhttp.nonProxyHosts=* <your vmargs>",

I have tried this, it does not work. Same error.

!ENTRY org.eclipse.core.net 1 0 2021-05-21 13:05:27.689
!MESSAGE System property http.nonProxyHosts has been set to * by an external source. This value will be overwritten using the values from the preferences

!ENTRY org.eclipse.core.net 1 0 2021-05-21 13:05:27.694
!MESSAGE System property https.nonProxyHosts has been set to * by an external source. This value will be overwritten using the values from the preferences

I have found a solution i think works though, but i'd like you to reproduce it if poss:

I created org.eclipse.core.net.prefs and copied this into $HOME/.vscode/data/User/workspaceStorage/$UUID/redhat.java/jdt_ws/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.core.net.prefs. After reloading the window, things resolved as normal and worked.

Example org.eclipse.core.net.prefs:

systemProxiesEnabled=false
proxiesEnabled=false
eclipse.preferences.version=1
nonProxiedHosts=*
org.eclipse.core.net.hasMigrated=true

@snjeza hope that makes sense.

Any update on this? The above fix isn't something I can really do every time as it will be reset if the workspace is cleaned up.
