[ironic] moving on

Hi ironic'ers, I'm moving on to a non-Ironic, non-OpenStack world. I'm glad to have been on this journey. The ironic community has been, and continues to be, great -- welcoming and helpful. Keep up the great work and the big visions [1]. I look forward to Ironic taking over the world ;) Thanks to everyone that I encountered; YOU are what made it so special and fun! --ruby [1] https://docs.openstack.org/ironic/latest/contributor/vision.html
