[searchlight][election][ptl] PTL non-candidacy

Hi guys, I have been taking the role of Searchlight's PTL since Stein to hopefully making the project sustainable. Over the course of 4 development cycles, I had lots of joy and also learned a lot while doing maintenance & open source contributor recruiting. Unfortunately, I switched to a job that does not involve OpenStack, and that leaves me no time for contributions. That being said, I announce my non-candidacy for the Wallaby cycle. Though not being able to contribute to the project, I'll still be around and help you out whenever I can. Thanks, -- *Trinh Nguyen* *dangtrinh.com <https://dangtrinh.com>*
