[ZEPPELIN-1730, 1587] add spark impersonation through --proxy-user option
### What is this PR for?
This is to add spark impersonation using --proxy-user option. note that it
enables also to use spark impersonation without having logged user as system
user with configured ssh.
### What type of PR is it?
Improvement
### Todos
* [x] - add `--proxy-user`
* [x] - try on standalone spark 1.6.2
* [x] - try on yarn-client mode spark 2.0.1
### What is the Jira issue?
Directly solves
[ZEPPELIN-1730](https://issues.apache.org/jira/browse/ZEPPELIN-1730) and also
solves [ZEPPELIN-1587](https://issues.apache.org/jira/browse/ZEPPELIN-1587)
according to discussion in #1566 since using `--proxy-user` in `spark-submit`
is preferable method.
### How should this be tested?
1. switch your spark cluster to `per user` and `isolated` mode
2. set up `user impersonation` flag
3. run some job using that spark interpreter
4. spark context should be created with currently logged in user
credentials on behalf of system user
### Screenshots (if appropriate)

yarn-client
