How to clean up orphan VisiNotify proxy objects

When VisiNotify suppliers/consumers are killed without disconnect_<> invocations from the application. The proxy objects are not clean up in the Visinotify.

Here are the sample steps to re-create the problem:

1. go to example in ${VBROKERDIR}/examples/vbroker/notify/basic_java
2. modify seqPushSupplier.java to comment out "consumer.disconnect_sequence_push_consumer()" line
3. run seqPushSupplier example
4. as ProxyPushConsumer servant is not properly cleaned up, it will be there after an hour
5. if this example is run X times, X number of orphan ProxyPushConsumer servant will be created and left alone
6. this can also be viewed from VBConsole

Resolution:

The way to clean up the resources are:

1. Shutdown Consumer/Supplier, visinotify and osagent.
2. delete the visinotify.dir in the /bin to cleanup the cache.
