[jira] [Created] (LIVY-450) Override config options by environment variables.

Alexey Romanenko created LIVY-450:
-------------------------------------

             Summary: Override config options by environment variables.
                 Key: LIVY-450
                 URL: https://issues.apache.org/jira/browse/LIVY-450
             Project: Livy
          Issue Type: Improvement
            Reporter: Alexey Romanenko


Add a possibility to override all config options by environment variables. 

For example:
 {{LIVY_SPARK_MASTER}} automatically overrides {{livy.spark.master}} and {{LIVY_SPARK_DEPLOY_MODE}} overrides {{livy.spark.deploy-mode}}.

It can be quite useful to use the same Livy image in different modes (local and cluster). 

Any pros/cons for or against that?
