Ports the first 118 tests from golang/nats-server/server/jetstream_cluster_1_test.go to C# integration tests in JetStream/JetStreamCluster1Tests.cs. Adds the Helpers/ scaffold (IntegrationTestBase, TestCluster, NatsTestClient, CheckHelper, ConfigHelper) and Xunit.SkippableFact package; tests skip automatically unless NATS_INTEGRATION_TESTS=true is set.
