Set ensembler log level to WARNING from INFO

[vinoth-gojek]

The default turing ensembler log level is set to INFO but this spams with too many logs thus causing memory consumption in downstream logging platform.

The goal of this very simple MR is to modify this log level to WARNING from INFO - python logging loglevels

Also there is an added capability for DS folks to change the ensembler log levels to INFO using env
