Barbicanclient CLI is too chatty

[Arun Kant]

Currently when using barbicanclient CLI, it always logs message in DEBUG mode. This creates problem when certain tooling script is expecting only certain response text in output. Please see following output of listing barbican secrets. Error message can be disregarded for purpose of this bug as its NOT related to reported behavior in CLI.

I believe this unintended behavior was added by this change (https://review.openstack.org/#/c/311138/) which exposed issue in cliff library where it sets DEBUG log level (https://github.com/openstack/cliff/blob/master/cliff/app.py#L204).

    Supress client debug messages

    cliff sets log level to DEBUG in `run` function [1], need to overwrite
    this configuration to depress DEBUG messages. This patch adds such
    configuration in `prepare_to_run_command` function which will be called
    by cliff after it sets log level to DEBUG [2][3].
