Bump gerritlib requirement to 0.10.0

With the recent upgrade of OpenDev's Gerrit deployment to 3.2, it
became apparent that group creation/detection in manage-projects
stopped working due to a behavior change with the Gerrit
command-line API. This was fixed in gerritlib 0.10.0 so we now
require at least that version.
