cloud-infra: fix generate-change-metadata.sh

After upgrading Gerrit, it appears that the endpoint being previously
used for querying change metadata changed format slightly. In the hope
of safeguarding against future upgrades, modifying the dependent change
metadata extraction piece to instead use command-line gerrit queries
over SSH.
