All kie-remote-* modules should be OSGi-friendly

Some modules in https://github.com/droolsjbpm/droolsjbpm-integration/tree/master/kie-remote are not OSGi-friendly (e.g. kie-remote-ws-common). All these modules need to be reviewed and fixed (using the <packaging>bundle</packaging>).

This may not apply for master as these modules will probably be removed. But it is still an issue for 6.5.x branch.
