Re: [I] [Bug(pd-store)] hstore backend api tests failure [incubator-hugegraph]

   After inspection, only the hstore API test `testMetricsBackend(org.apache.hugegraph.api.MetricsApiTest)` has not passed. The reason is that the hstore backend has not set up the corresponding metrics. Considering that the PD metrics are currently unavailable:
   
   1. The `PdMetricsAPI` fetches metrics information from the PD meta store, which depends on the server periodically reporting metrics to PD (not yet adapted  https://github.com/hugegraph/server/tree/master/hugegraph-api/src/main/java/org/apache/hugegraph/metrics).
   2. It seems that `PDMetrics` is not connected to the PD metrics API.
   
   Therefore, a temporary solution is to directly query the PD gRPC interface in the session to check the number of stores, bypassing the PD metrics API for now.
