deps: bump bollard 0.18 to 0.20, update VDI Docker driver

Bollard 0.20 moved container option types from bollard::container to
bollard::query_parameters, replaced Config<T> with ContainerCreateBody,
and changed several fields to Option types. Update all imports and call
sites in the VDI Docker driver accordingly.
