how to set persister log level

[like-inspur]

I want to set warn log level for monasca persister. So I set DEBUG and VERBOSE both are "false", but monasca persister pod still output INFO log. The config and output are like this:
spec:
containers:
- env:
- name: DEBUG
value: "false"
- name: VERBOSE
value: "false"

Hi, hmm, looks like it was somehow overlooked.
Sorry about this, it's need to be improved.

I created change to monasca-persister to allow configuring log levels on https://review.openstack.org/#/c/652992
When it's merged it will be possible to use them in docker images build from monasca-persister repository. This images are still not pushed to docker hub (it's in progress https://review.openstack.org/#/c/652650/ )
