Upgrade to OpenDAL Core v0.50

Public API

services-postgresql's connect string now supports only URL format

Previously, it supports both URL format and key-value format. After switching the implementation from tokio-postgres to sqlx, the service now supports only the URL format.

list now returns path itself

Previously, list("a/b") would not return a/b even if it does exist. Since v0.50.0, this behavior has been changed. OpenDAL will now return the path itself if it exists. This change applies to all cases, whether the path is a directory or a file.

Refactoring of the metrics-related layer

In OpenDAL v0.50.0, we did a refactor on all metrics-related layers. They are now sharing the same underlying implemenationts. PrometheusLayer, PrometheusClientLayer and MetricsLayer are now have similar public APIs and exactly the same metrics value.
