…rics StarRocks FE introduced two summary metrics for slow-lock observability in StarRocks/starrocks#66027 (back-ported to 4.0/3.5): - starrocks_fe_slow_lock_held_time_ms — how long locks were held when slow locks were detected (max across owners). - starrocks_fe_slow_lock_wait_time_ms — how long waiters waited before the lock was acquired. Both are emitted as Prometheus summary (quantiles 0.75/0.95/0.98/0.99/0.999 plus _sum / _count), so map them with the same three-line pattern already used by other histogram metrics in this integration. Add corresponding metadata.csv entries. Bump version to 1.3.0 and update CHANGELOG + README. Signed-off-by: Planck Li <jaogoy@gmail.com>

Also regenerate config_models/{defaults,instance}.py via `ddev validate models celerdata -s` (ddev 16.1.1) — the generated files had drifted from their spec.yaml source since the previous sync in 1.2.0, which CI flags as out-of-sync. These changes are auto-generated and not behavioral. Signed-off-by: Planck Li <jaogoy@gmail.com>

It's important to monitor the lock info when the cluster is pending for a lot of loadings and queries.
