We need to improve the overall messages that are shown in hydrator.
1. 01/18/16 9:18:12 am: Validation success! Pipeline MyPipeline is valid.
- Can be "01/18/16 9:18:12 am: Pipeline 'MyPipeline' is valid."
2. No messages as of now.
- We don't need to display this message. The screen can be just empty.
3. Draft MyPipeline saved successfully.
- Can be: "Pipeline 'Mypipeline' saved as draft"
4. 01/18/16 9:27:45 am: Stream is missing connection
- Can be "01/18/16 9:27:45 am: Stream source '<name of the label>' is missing connection"
Similarly for other plugin types.
