[LOG4J2-1015] Add a way to route messages based on the %marker in Layout

log event with the <code>SQL</code> marker to
<code>sql.log</code>, the log event with the <code>PAYLOAD</code>
marker to <code>payload.log</code>, and so on.

+ You can use the notation <code>"${marker:name}"</code> and
<code>"$${marker:name}"</code> to check for the
+ existence of a marker where <code>name</code> is the marker name.
If the marker exists, the expression returns
+ the name, otherwise <code>null</code>.
