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.

golint, scopelint and interfacer are deprecated. golint is replaced by
revive. This linter is better because it will also check for our error
style: `error strings should not be capitalized or end with punctuation or a newline`
scopelint is replaced by exportloopref (already endabled)
interfacer has no replacement but I do not think this linter is
important.

Because /etc/hosts is shared for all containers with a shared network
namespace you should not be able to add hosts from a joined container.
Only the primary netns container can set the hosts.

From a security point of view, it would be nice to be able to map a
rootless usernamespace that does not use your own UID within the
container.
This would add protection against a hostile process escapping the
container and reading content in your homedir.

`DefineCreateFlags` was excluding clone from using the memory-swappiness flag leading the value to be zero

When podman gets an error it prints out "Error: " before
printing the error string. If the error message starts with
error, we end up with
Error: error ...
This PR Removes all of these stutters.
logrus.Error() also prints out that this is an error, so no need for the
error stutter.

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
