publish the apikit-plugin as well as a classifier of apikit-module

[juancavallotti]

Currently, the mule-module-apikit-plugin-.zip artifact is being published with separate maven coordinates, it would be good if it can be published under the 'plugin' classifier with the same apikit coordinates, i.e.

<groupId>org.mule.modules</groupId>
<artifactId>mule-module-apikit</artifactId>
<version>1.2</version>
<classifier>plugin</classifier>
<type>zip</type>

This way it would follow the same conventions as the other cloud connectors.
