Enable colored output for loggingLOG-380-shared
ColorFormatter class uses ANSI esacpe sequences to render logging message in color, it uses standard colors so it should workd on any UNIX terminal. Make markerFormatter class to inherits from colorFormatter. Change-Id: Ie24a06df861ca5d07796e78dea7e875daf149380 Issue-ID: MULTICLOUD-329 Signed-off-by: liangke <lokyse@163.com>
