Created jobs for nodejs version 6

This patch creates two job groups for nodejs6, as well as job
templates for the same. They follow the exact same pattern as
nodejs version 4 templates, to simplify creating an upgrade path.

These jobs have been set to non-voting, and have been added to
the js-openstack-lib project.
