Properly integrate DMR configuration model with Host Environment and Server Environment

When users update items in the DMR configuration model that are also reflected in ServerEnvironment or HostEnvironment, synchronization needs to take place. This can either be:

1) The XXEnvironment class is updated. For example if the server name is set via xml, that should be recorded in ServerEnvironment and any auto-created system properties (e.g. jboss.node.name) should be updated (but only if they were auto-created, not if set by the user.)

2) The configuration change is rejected. For example, the user tries to change jboss.home.dir via the <system-properties> elements in standalone.xml.
