upaas reads its settings with the UPAAS_ prefix (only PORT is also read
without it), so the table's DEBUG, SENTRY_DSN, METRICS_USERNAME and
METRICS_PASSWORD were silently ignored when set as written. The rows now
read UPAAS_DEBUG, UPAAS_SENTRY_DSN, UPAAS_METRICS_USERNAME and
UPAAS_METRICS_PASSWORD, and the UPAAS_HOST_DATA_DIR description refers to
UPAAS_DATA_DIR. TODO.md records the step.
