[MNG-7523] Backport MAVEN_ARGS support to 3.8.x

[hgschmie]

https://maven.apache.org/configure.html shows the MAVEN_ARGS
environment variable which is extremely useful for customizing build
scripts and processes. Unfortunately, it is only support for (unreleased)
Maven 4.

This patch backports support to Maven 3.8.x in the hope that this
support would arrive much sooner than with Maven 4.x.x

Following this checklist to help us incorporate your
contribution quickly and easily:

• Make sure there is a JIRA issue filed
  for the change (usually before you start working on it). Trivial changes like typos do not
  require a JIRA issue. Your pull request should address just this issue, without
  pulling in other changes.
• Each commit in the pull request should have a meaningful subject line and body.
• Format the pull request title like [MNG-XXX] SUMMARY, where you replace MNG-XXX
  and SUMMARY with the appropriate JIRA issue. Best practice is to use the JIRA issue
  title in the pull request title and in the first line of the commit message.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Run mvn clean verify to make sure basic checks pass. A more thorough check will
  be performed on your pull request automatically.
• You have run the Core IT successfully.

If your pull request is about ~20 lines of code you don't need to sign an
Individual Contributor License Agreement if you are unsure
please ask on the developers list.
