Ability to configure Intellij VM args

[hohwille]

As a IDEasy and Intellij user, I want to be able to configure VM args so that my Intellij does not run out of memory for my large project codebase.

Currently I manually have to increase the max Java heap size in Intellij via -Xmx option:
https://www.jetbrains.com/help/idea/tuning-the-ide.html#configure-jvm-options

So these VM args are stored in a OS specific *.vmoptions file inside the Intellij installation.
Whenever intellij gets updated, the process needs to be repeated so this is currently rather tedious.
For a project with a large team where development requires tuning of this VM args by every developer an automated approach would be needed.

Implementation suggestion

Ideally we can find a way to pass additional VM args to intellij via CLI dynamically and like with ECLIPSE_VMARGS introduce a INTELLIJ_VMARGS variable for that with ability to configure via ide.properties with potential overriding in different locations.

If really not possible, we would need to have a very specific custom logic in our Intellij commandlet that would tweak the *.vmoptions file accordingly before launching idea. This approach would be much more complicated and would manipulate the installation what we typically want to avoid (best practice: keep installations pristine - see sandbox)
