Feature: allow passing extra vmargs to jdt

[diasbruno]

Hi,

This patch allow users to set more Java VM args (helpful if using lombok).

Example:

(setq eglot-eclipse-jdt-extra-vmargs
      (list "-noverify"
            "-Xmx1G"
            "-XX:+UseG1GC"
            "-XX:+UseStringDeduplication"
            "-javaagent:/path/to/lombok/lombok-1.18.6.jar"
            "-Xbootclasspath/a:/path/to/lombok/lombok-1.18.6.jar"))

Thanks for the PR, however I think a better approach is to provide a way for users to subclass eglot-eclipse-jdt or modify the entry in eglot-server-programsrather than providing a customization variable. Do you want to try that instead?

We've already discussed this customization issue before, specifically for the Eclipse JDT server. @joaotavora decided not to provide server-specific customization variables, because eglot is minimalist by design.

Thanks, @mkcms. No problem, I'll give it a try.

@diasbruno Hi! Did you make any progress here?

Hi @skangas, I didn't have a chance to look this.

I think this was recently fixed by the changes described in annoucement #868. See also #911 for a success story.
