By replacing grpc with ttrpc, we can reduce total memory runtime
requirements and binary size. With minimal code changes, the shim can
now be controlled by the much lightweight protocol, reducing the total
memory required per container.
When reviewing this change, take particular notice of the generated shim
code.

Synchronous image delete provides an option image delete to wait
until the next garbage collection deletes after an image is removed
before returning success to the caller.

Currently the output for a non-existent image reference and a valid
image reference is exactly the same on `ctr images remove`. Instead of
outputting the target ref input, if it is "not found" we should alert
the user in case of a mispelling, but continue not to make it a failure
for the command (given it supports multiple ref entries)

This patch changes the output of `ctr version` to align version and revision.
It also changes `.Printf()` to `.Println()`, to make the code slightly easier
to read.

To reduce the binary size of containerd, we no longer import the
`server` package for only a few defaults. This reduces the size of `ctr`
by 2MB. There are probably other gains elsewhere.

This keeps the semantics the same as the other commands to only list
containers, tasks, images by calling the list subcommand.

Allow a user provided name for the checkpoint as well as a default
generated name for the checkpoint image.
Signed-off-by: Michael Crosby <crosbymichael@gmail.com>
This allows one to manage the checkpoints by using the `ctr image`
command.
The image is created with label "containerd.io/checkpoint". By
default, it is not included in the output of `ctr images ls`.
We can list the images by using the following command:
$ ctr images ls labels.containerd.\"io/checkpoint\"==true
