// CmdSet stores a new image in the graph.
// Images are stored in the graph using 4 elements:
// - A user-defined ID
// - A collection of metadata describing the image
// - A directory tree stored as a tar archive (also called the "layer")
// - A reference to a "parent" ID on top of which the layer should be applied
//
// NOTE: even though the parent ID is only useful in relation to the layer and how
// to apply it (ie you could represent the full directory tree as 'parent_layer + layer',
// it is treated as a top-level property of the image. This is an artifact of early
// design and should probably be cleaned up in the future to simplify the design.
//
// Syntax: image_set ID
// Input:
// - Layer content must be streamed in tar format on stdin. An empty input is
// valid and represents a nil layer.
//
// - Image metadata must be passed in the command environment.
// 'json': a json-encoded object with all image metadata.
// It will be stored as-is, without any encoding/decoding artifacts.
// That is a requirement of the current registry client implementation,
// because a re-encoded json might invalidate the image checksum at
// the next upload, even with functionaly identical content.
