Nuxeo Drive should be released with the platform

For now nuxeo-drive is not part of the released addons, the module being declared in addons/pom-optionals.xml and not addons/pom.xml. This is because the nuxeo-drive-jsf module needs to embed the Nuxeo Drive client binaries (.msi and .dmg) which are built by the Jenkins jobs listed below, through the maven-antrun-plugin at build time.

http://qa.nuxeo.org/jenkins/job/addons_nuxeo-drive-master-msi/
http://qa.nuxeo.org/jenkins/job/addons_nuxeo-drive-master-dmg/
http://qa.nuxeo.org/jenkins/job/addons_nuxeo-drive-5.6.0-msi/
http://qa.nuxeo.org/jenkins/job/addons_nuxeo-drive-5.6.0-dmg/

This is a problem at least because:

• we need to use a separate job to release nuxeo-drive: https://qa.nuxeo.org/jenkins/job/IT-release-on-demand-addon/
• nuxeo-drive might not be released when the platform is (if we forget to do the separate release), this is an issue especially when releasing hotfixes

Instead we should use a configuration template to externalize these binaries and use the marketplace package to include it, see https://github.com/nuxeo/marketplace-drive.
