Describe the bug

I found this discuss in grpc, they have fix this. @caojiajun

I have confirm that 0.7.7 is working for it.

1. reproduce it, working with jetcd 0.7.6 and netty 4.1.101.Final. Test case will failed.
2. check jetcd 0.7.7 and test case successed.

   @Test
    public void testWatch() throws InterruptedException {
        String prefix = "/";
        ClientBuilder clientBuilder = Client.builder()
                .endpoints("http://192.168.3.87:2379");
        Client client = clientBuilder.build();

        AtomicBoolean haveWatch = new AtomicBoolean(false);
        Watch.Watcher watcher = client.getWatchClient().watch(ByteSequence.from(prefix.getBytes()),
                WatchOption.newBuilder().isPrefix(true).withPrevKV(true).build(),
                new Watch.Listener() {
                    @Override
                    public void onNext(WatchResponse watchResponse) {
                        haveWatch.set(true);
                    }

                    @Override
                    public void onError(Throwable throwable) {
                    }

                    @Override
                    public void onCompleted() {
                    }
                });

        KV kvClient = client.getKVClient();
        kvClient.put(ByteSequence.from("/hello", Charset.defaultCharset()),ByteSequence.from("world", Charset.defaultCharset())).join();

        TimeUnit.SECONDS.sleep(2);
        Assertions.assertTrue(haveWatch.get());
        watcher.close();
        kvClient.close();
        client.close();
    }

I manually upgraded the grpc and it worked

[caojiajun]

it worked after upgrade to netty-4.1.106 and jetcd-0.7.7

@caojiajun cool, so this issue should be closed?
