The LCOW implementation in dockerd has been deprecated in favor of re-implementation in containerd (in progress). Microsoft started removing the LCOW V1 code from the build dependencies we use in Microsoft/opengcs (soon to be part of Microsoft/hcshhim), which means that we need to start removing this code. This first step removes the lcow graphdriver, the LCOW initialization code, and some LCOW-related utilities. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
