includes:

- microsoft/hcsshim#718 wclayer: Work around Windows bug when expanding sandbox size
    - fixes microsoft/hcsshim#708 Windows Host Compute Service bug breaks docker (and other) sandboxes bigger than 20G on Windows 1903
    - fixes microsoft/hcsshim#624The hcsshim on Windows 10 1903 always fails to build Docker image
    - fixes/addresses docker/for-win#3884 An error occurred while attempting to build Docker image (especially this comment and the next comments after: https://github.com/docker/for-win/issues/3884#issuecomment-498939672)
    - fixes/addresses docker/for-win#4100 Windows 1903 fails when storage-opt used
    - fixes moby/moby#36831 hcsshim::PrepareLayer failed in Win32: The parameter is incorrect (https://github.com/moby/moby/issues/36831#issuecomment-498612392)
    - fixes Stannieman/audacity-with-asio-builder#5 Docker won't build container
    - fixes MicrosoftDocs/visualstudio-docs#3523 Error when running build with storage-opts set
    - fixes moby/moby#39524 Docker build windows 19.03 --storage-opt size>20G

Note that this is a temporary workaround for a bug in the platform, and will be reverted once that is addressed:

- microsoft/hcsshim#721 Revert 718 when Windows 19H1 has expand sandbox fix
