Example #1: List tenants

import io.chirpstack.api.*;
import io.grpc.ManagedChannel;
import io.grpc.ManagedChannelBuilder;
import io.grpc.Metadata;
import io.grpc.stub.MetadataUtils;

public class ChirpStack {
    public static void main(String[] args) {
        ManagedChannel channel = ManagedChannelBuilder
            .forAddress("localhost", 8080)
            .usePlaintext()
            .build();
        Metadata metadata = new Metadata();
        Metadata.Key<String> key = Metadata.Key.of("authorization", Metadata.ASCII_STRING_MARSHALLER);
        String token = "Bearer <INSERT_TOKEN_HERE>";
        metadata.put(key, token);
        TenantServiceGrpc.TenantServiceBlockingStub stub = TenantServiceGrpc
            .newBlockingStub(channel)
            .withInterceptors(MetadataUtils.newAttachHeadersInterceptor(metadata));
        ListTenantsRequest request = ListTenantsRequest.newBuilder()
            .setLimit(10)
            .build();
        ListTenantsResponse response = stub.list(request);
        System.out.println("Number of tenants: " + response.getResultCount());
