Fabricio Voznika 0e07c94d54 Kill sandbox process when 'runsc do' exits

Fabricio Voznika bdb19b82ef Add Container/Sandbox args struct for creation
There were 3 string arguments that could be easily misplaced
and it makes it easier to add new arguments, especially for
Container that has dozens of callers.

Fabricio Voznika 356d1be140 Allow 'runsc do' to run without root
'--rootless' flag lets a non-root user execute 'runsc do'.
The drawback is that the sandbox and gofer processes will
run as root inside a user namespace that is mapped to the
caller's user, intead of nobody. And network is defaulted
to '--network=host' inside the root network namespace. On
the bright side, it's very convenient for testing:

runsc --rootless do ls
runsc --rootless do curl www.google.com

Fabricio Voznika c1be25b78d Scrub runsc error messages
Removed "error" and "failed to" prefix that don't add value
from messages. Adjusted a few other messages.  In particular,
when the container fail to start, the message returned is easier
for humans to read:

$ docker run --rm --runtime=runsc alpine foobar
docker: Error response from daemon: OCI runtime start failed: <path> did not terminate sucessfully: starting container: starting root container [foobar]: starting sandbox: searching for executable "foobar", cwd: "/", $PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin": no such file or directory

Closes #77

Justine Olshan c05660373e Moved restore code out of create and made to be called after create.
Docker expects containers to be created before they are restored.
However, gVisor restoring requires specificactions regarding the kernel
and the file system. These actions were originally in booting the sandbox.

Now setting up the file system is deferred until a call to a call to
runsc start. In the restore case, the kernel is destroyed and a new kernel
is created in the same process, as we need the same process for Docker.

These changes required careful execution of concurrent processes which
required the use of a channel.

Full docker integration still needs the ability to restore into the same
container.

Justine Olshan 80bdf8a406 Sets the restore environment for restoring a container.
Updated how restoring occurs through boot.go with a separate Restore function.
This prevents a new process and new mounts from being created.
Added tests to ensure the container is restored.
Registered checkpoint and restore commands so they can be used.
Docker support for these commands is still limited.
Working on #80.

Brielle Broder e1aee51d09 Modified Checkpoint/Restore flags to improve compatibility with Docker.
Added a number of unimplemented flags required for using runsc's
Checkpoint and Restore with Docker. Modified the "image-path" flag to
require a directory instead of a file.

Brielle Broder 7d6149063a Restore implementation added to runsc.
Restore creates a new container and uses the given image-path to load a saved
image of a previous container. Restore command is plumbed through container
and sandbox. This command does not work yet - more to come.

Googler 0c34b460f2 Add runsc checkpoint command.
Checkpoint command is plumbed through container and sandbox.
Restore has also been added but it is only a stub. None of this
works yet. More changes to come.
