Implement a feature allowing the bot to move issues around on the
project board:
When a change's commit message includes "WIP" or "DNM",
the issue will be moved to the "In Progress" column.
When a change's commit message does not include "WIP" or "DNM",
assume that the change is ready for review, and move it to the
"Submitted on Gerrit" column.
