Replace deprecated ioutil
Package `io/ioutil` was deprecated in golang 1.16, preventing podman from
building under Fedora 37.  Fortunately, functionality identical
replacements are provided by the packages `io` and `os`.  Replace all
usage of all `io/ioutil` symbols with appropriate substitutions
according to the golang docs.

Fix stutters
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.

Valentin Rothberg aad29e759c health check: add on-failure actions
For systems that have extreme robustness requirements (edge devices,
particularly those in difficult to access environments), it is important
that applications continue running in all circumstances. When the
application fails, Podman must restart it automatically to provide this
robustness. Otherwise, these devices may require customer IT to
physically gain access to restart, which can be prohibitively difficult.

Add a new `--on-failure` flag that supports four actions:

- **none**: Take no action.

- **kill**: Kill the container.

- **restart**: Restart the container.  Do not combine the `restart`
               action with the `--restart` flag.  When running inside of
               a systemd unit, consider using the `kill` or `stop`
               action instead to make use of systemd's restart policy.

- **stop**: Stop the container.

To remain backwards compatible, **none** is the default action.

Jake Correnti 5633ef1d15 Docker-compose disable healthcheck properly handled
Previously, if a container had healthchecks disabled in the
docker-compose.yml file and the user did a `podman inspect <container>`,
they would have an incorrect output:

```
"Healthcheck":{
   "Test":[
      "CMD-SHELL",
      "NONE"
   ],
   "Interval":30000000000,
   "Timeout":30000000000,
   "Retries":3
}
```

After a quick change, the correct output is now the result:
```
"Healthcheck":{
   "Test":[
      "NONE"
   ]
}
```

Additionally, I extracted the hard-coded strings that were used for
comparisons into constants in `libpod/define` to prevent a similar issue
from recurring.

enable gocritic linter
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.

cdoern 94df701512 Implement Podman Container Clone
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
--memory
--run
