windows的docker开始支持linux的镜像 ，Version 18.03.0-ce-win59 (16762)

LCOW containers can now be run next to Windows containers.
Use '--platform=linux' in Windows container mode to run Linux images.
This is an experimental feature; If you want to disable Daemon 'experimental' option and had pull lcow images, you must reset to default or the windows daemon will not start.
