Description

expression is confusing. It is used for both default-value, and to allow configuration of what system property to accept. However, now that default-value takes expressions, it is redundant for that and can be confusing, and because of its legacy in handling that, it is in the wrong order for system property handling (see MNG-2062).

I propose we deprecate expression in favour of default-value, and add system-property="someProperty" as the way to configure what command line option can be used.
