jms message handling

1. not ignoring exceptions while sending messages
2. Sends 1 message to falcon system topic and 1 to user entity topic for both feed and process
3. Handing drop partition in hcat for DELETE operation
4. Removed caching on HCatClient as it creates issues during hcat restarts
We do not register any partition if the path doesn't exist. Its same as output feed doesn't exist if there is no output path. I do not see any cases where the partition is required without the data path? Do you see any?
