[ZEPPELIN- 1298] Log instead of throwing trace for ping messages
### What is this PR for?
When non authenticated user in non-anonymous mode tries to send any
websocket api message it results in throwing a traceback. However on PING
message we don't need to show the whole traceback and we can just log in order
not to pollute the logs file.
### What type of PR is it?
Hot Fix
### Todos
* [x] - log and return on PING
### What is the Jira issue?
[Zeppelin-1298](https://issues.apache.org/jira/browse/ZEPPELIN-1298)
### How should this be tested?
Follow the steps in issue and shouldn't get repeating traceback.
### Screenshots (if appropriate)
### Questions:
* Does the licenses files need update? no
* Is there breaking changes for older versions? no
* Does this needs documentation? no

don't throw exception on ping
in anonymous not allowed mode normally any nonauthenticated websocket
message should throw an error, but ping doesn't do any job and no need to throw
on it probably, just return and log
