[feature] Reimplemented send message function using xquery Maps:

xquery version "3.0";

import module namespace jms="http://exist-db.org/xquery/messaging" at "java:org.exist.messaging.xquery.MessagingModule";

let $jmsconfig :=
    map {
        "java.naming.factory.initial" := "org.apache.activemq.jndi.ActiveMQInitialContextFactory",
        "java.naming.provider.url" := "tcp://myserver.local:61616",
        "Destination" := "dynamicTopics/testtopic",
        "ConnectionFactory" := "ConnectionFactory"
    }

let $meta :=
    map {
        "Foo" := "Bar",
    }

return jms:send( "a" , $meta, $jmsconfig)
