Going to replace all the FLAGS with cfg.CONF

[Vincent Hou]

Many parts of cinder code are using FLAGS still. I suggest we replace them with the cfg.CONF.

Some issues may retain if we do not do the replacement. For example, oslo is fixing a bug (https://bugs.launchpad.net/oslo/+bug/1176817). The parameter sql_connection will still take no effect for user-specified value, though (https://bugs.launchpad.net/oslo/+bug/1176817) is fixed.

Hi Vincent,

I don't see the connection between giving CLI option priority over config-file and cinder using FLAGS. Could you elaborate?
