> Clean up notion between user properties and system properties

> URL: https://issues.apache.org/jira/browse/MNG-7556
> Project: Maven

>
> For a very long time we have documented that the user can set system
> properties via {{mvn -Dfoo=bar}}, but actually those are user properties
> which are promoted to system properties and it some cases system properties
> cannot be modified *after* the JVM has been started. To properly set system
> properties there are basically two ways:
> * use {{MAVEN_OPTS}} environment variable
> * use {{.mvn/jvm.config}} file
> A third option in the future we could introduce, like other Java tools, a
> {{-J-Dfoo=bar}} option with the restriction of the the paragraph above.
