ZEPPELIN-1225. Errors before the last shell command are ignored
### What is this PR for?
The problem is that command "bash -c <shell scripts>" will always return 0
as long as the last line of shell script run correctly. e.g the following
command will run correctly without any error message.
```
hello
pwd
```
This PR will redirect stderr and stdout to the same place, and will display
both the stderr and stdout to frontend just like what user see in the native
shell terminal. So the output of above command will be as following
```
bash: hello: command not found
/Users/jzhang/github/zeppelin
```
### What type of PR is it?

* https://issues.apache.org/jira/browse/ZEPPELIN-1225

* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No
