image cache is logging warnings when not enabled

[Patrick East]

The image cache is logging this warning but it isn't even enabled:

 http://logstash.openstack.org/#dashboard/file/logstash.json?query=message%3A%5C%22Unable%20to%20get%20Cinder%20internal%20context%2C%20will%20not%20use%20image-volume%20cache.%5C%22%20AND%20tags%3A%5C%22screen-c-vol.txt%5C%22%20AND%20voting%3A%5C%221%5C%22

While disabled there shouldn't be any log output complaining about the internal tenant being available or not.

We probably don't want this message to be a warning either, there is already one about failing to create the internal context so this is kind of redundant (and verbose).

    Don’t log warnings for image cache when disabled

    Right now we do a check for the internal tenant and log a warning before
    we check to see if the cache is even turned on for that backend. We
    should be only checking for the internal tenant if the image cache has
    been configured for the backend.

    In addition we shouldn’t log a warning for this since there is already
    a warning for the internal context when we try and create it if it is
    not configured correctly… to reduce the warning spam this change
    switches the log message to an info level.
