Add Macro execution support on context listener

[aliokan]

When I don't need to adapt something, I want be able to use Macro instead of MacroAdapterStrategy.

<listen ref="StatusService">
    <event static-ref="message.ServiceMessage.OFFLINE" strategy="adapter.switch.SwitchStatusServiceMessageStrategy"/>
</listen>

Like state event :

<state id="assemblingEnd" ref="state.ASSEMBLING_END">
    <enter command-class="adapter.bootstrap.BootstrapMacro" fire-once="true"/>
</state>

We would like to target something like this at the end

<listen ref="StatusService">
    <event ref="messageID" command-class="pack.CommandClass"/>
</listen>
