This addresses the first issue reported in #59. CRI-O expects runsc to
return success to delete when --force is used with a non-existing container.

Container user might not have enough priviledge to walk directories and
mount filesystems. Instead, create superuser to perform these steps of
the configuration.

This is another step towards multi-container support.
Previously, we delivered signals directly to the sandbox process (which then
forwarded the signal to PID 1 inside the sandbox). Similarly, we waited on a
container by waiting on the sandbox process itself. This approach will not work
when there are multiple containers inside the sandbox, and we need to
signal/wait on individual containers.
This CL adds two new messages, ContainerSignal and ContainerWait. These
messages include the id of the container to signal/wait. The controller inside
the sandbox receives these messages and signals/waits on the appropriate
process inside the sandbox.
The container id is plumbed into the sandbox, but it currently is not used. We
still end up signaling/waiting on PID 1 in all cases. Once we actually have
multiple containers inside the sandbox, we will need to keep some sort of map
of container id -> pid (or possibly pid namespace), and signal/kill the
appropriate process for the container.

This is a necessary prerequisite for supporting multiple containers in a single
sandbox.
All the commands (in cmd package) now call operations on Containers (container
package). When a Container first starts, it will create a Sandbox with the same
ID.
The Sandbox class is now simpler, as it only knows how to create boot/gofer
processes, and how to forward commands into the running boot process.
There are TODOs sprinkled around for additional support for multiple
containers. Most notably, we need to detect when a container is intended to run
in an existing sandbox (by reading the metadata), and then have some way to
signal to the sandbox to start a new container. Other urpc calls into the
sandbox need to pass the container ID, so the sandbox can run the operation on
the given container. These are only half-plummed through right now.

os.Rename validates that the target doesn't exist, which is different from
syscall.Rename which replace the target if both are directories. fsgofer needs
the syscall behavior.

When file is backed by host FD, atime and mtime for the host file and the
cached attributes in the Sentry must be close together. In this case,
the call to update atime and mtime can be skipped. This is important when
host filesystem is using overlay because updating atime and mtime explicitly
forces a copy up for every file that is touched.

This is to allow files mapped directly, like /etc/hosts, to be writable.

Two changes in this CL:
First, make the "boot" process sleep when it encounters an error to give the
controller time to send the error back to the "start" process. Otherwise the
"boot" process exits immediately and the control connection errors with EOF.
Secondly, open the log file with O_APPEND, not O_TRUNC. Docker uses the same
log file for all runtime commands, and setting O_TRUNC causes them to get
destroyed. Furthermore, containerd parses these log files in the event of an
error, and it does not like the file being truncated out from underneath it.
Now, when trying to run a binary that does not exist in the image, the error
message is more reasonable:
$ docker run alpine /not/found
docker: Error response from daemon: OCI runtime start failed: /usr/local/google/docker/runtimes/runscd did not terminate sucessfully: error starting sandbox: error starting application [/not/found]: failed to create init process: no such file or directory
Fixes #32

Detachable exec commands are handled in the client entirely and the detach option is not used anymore.
