Description

If there is no connection to amazonaws, app will wait for 2 minutes during setup:

Even if Amazon S3 notebook storage wasn't configured Helium goes to zeppelin.notebook.s3.endpoint.

It would be nice if we could set timeout for s3 bucket if we know that there is no connection to amazonaws.
