Reserved annotations are used internally by Podman and would effect
nothing when run with Kubernetes so we should not be generating these

Podman adds an Error: to every error message. So starting an error
message with "error" ends up being reported to the user as
Error: error ...
This patch removes the stutter.
Also ioutil.ReadFile errors report the Path, so wrapping the err message
with the path causes a stutter.

Following PR adds support for running containers from a manifest list
present on localstorage. Before this PR podman only supports running
containers from valid images but not from manifest list.
So `podman run -it --platform <some> <manifest-list> command` should
become functional now and users should be able to resolve images on the
bases of provided `--platform` string.
Example
```
podman manifest create test
podman build --platform linux/amd64,linux/arm64 --manifest test .
podman run --rm --platform linux/arm64/v8 test uname -a

The linter ensures a common code style.
- use switch/case instead of else if
- use if instead of switch/case for single case statement
- add space between comment and text
- detect the use of defer with os.Exit()
- use short form var += "..." instead of var = var + "..."
- detect problems with append()
```
newSlice := append(orgSlice, val)
```
This could lead to nasty bugs because the orgSlice will be changed in
place if it has enough capacity too hold the new elements. Thus we
newSlice might not be a copy.
Of course most of the changes are just cosmetic and do not cause any
logic errors but I think it is a good idea to enforce a common style.
This should help maintainability.

podman container clone takes the id of an existing continer and creates a specgen from the given container's config
recreating all proper namespaces and overriding spec options like resource limits and the container name if given in the cli options
this command utilizes the common function DefineCreateFlags meaning that we can funnel as many create options as we want
into clone over time allowing the user to clone with as much or as little of the original config as they want.
container clone takes a second argument which is a new name and a third argument which is an image name to use instead of the original container's
the current supported flags are:
--destroy (remove the original container)
--name (new ctr name)
--cpus (sets cpu period and quota)
--cpuset-cpus
--cpu-period
--cpu-rt-period
--cpu-rt-runtime
--cpu-shares
--cpuset-mems

this commit fixes two bugs and adds regression tests.
when getting healthcheck values from an image, if the image does not
have a timeout defined, this resulted in a 0 value for timeout. The
default as described in the man pages is 30s.
when inspecting a container with a healthcheck command, a customer
observed that the &, <, and > characters were being converted into a
unicode escape value. It turns out json marshalling will by default
coerce string values to ut8.

Podman adds a few environment variables by default, and
currently there is no way to get rid of them from your container.

want.
--unsetenv-all will remove all default environment variables.

containers.conf or from the container image.

inspection of images. Previously, only the size computation was
optional, now the one for the parent image is as well.

on my local machine. With this change, we cut off 10ms from many code
paths, most importantly, container creation.

this is the first pass at implementing init containers for podman pods.
init containersare made popular by k8s as a way to run setup for pods
before the pods standard containers run.
unlike k8s, we support two styles of init containers: always and
oneshot. always means the container stays in the pod and starts
whenever a pod is started. this does not apply to pods restarting.
oneshot means the container runs onetime when the pod starts and then is
removed.
