Without any swap space enabled, it's possible some intensive operation
can chew up all the memory on the test VM. Enabling swap space will
prevent this for minor cases, but could lead to disk-thrashing if the
memory demand is excessive.
Since the test system never reboots, using a file-backed swap should
suffice. Though not ideal, it's easy to setup and doesn't require any
interactions with the cloud that owns the VM or the job that created it.

The getCommand func strips out unwanted characters around the
command of the container. The JSON output should use this func
like the regular ps output for both consistency and because
Python does a literal interpretation of the bracket [] characters
when consuming as JSON.

Some kpod commands were listed twice in main.go. Removed these
duplicates and alphabetized the remaining commands to prevent this
from happening in the future

Consumers of the json output, like the atomic cli, need the ID of the
image for the container as well as the name. Specifically, it is used
to tract "used" and "vulnerable" images.

Have the "kpod info" command also package up the driver-level status
information that the github.com/containers/storage.Store's Status()
method returns.

Found out that during OpenShift testing, node was trying to remove
containers (probably in a bad state) and was failing the removal with
this kind of error:
E0828 13:19:46.082710 1235 kuberuntime_gc.go:127] Failed to remove
container
"e907f0f46b969e0dc83ca82c03ae7dd072cfe4155341e4521223d9fe3dec5afb": rpc
error: code = 2 desc = failed to remove container exit file

I believe it's ok to ignore this error as it may happen conmon will
fail early before exit file is written.

No reason to carry this temporary variable for documentation purposes.
If in the future we find that it is necessary to add a CLI option, we
can add the variable then.

Changed the JSON output to hold the actual type of the data.
For example the creation time of a container will be of form time.Time.
The human readable output modifies all the fields to type string, which
is not helpful when the JSON output wants to be used for further processing.

ln -s errors out with file exists if you run make install.systemd twice
or more. This patch installs the alias directly w/o using a symlink so
it can be run multiple times w/o errors.

SetMaxThreads from runtime/debug in Golang is called to set max threads
value to 90% of /proc/sys/kernel/threads-max
Should really help performance.
