podman system reset removed machines incorrectly

Report correct RemoteURI
Rather than assuming a filesystem path, the API service URI is recorded
in the libpod runtime configuration and then reported as requested.

Note: All schemes other than "unix" are hard-coded to report URI exists.

Fixes #12023

shell completion --format: use structs by reference
For the AutocompleteFormat function we expect the correct template
struct which is used in the golang template. The function can handle
both struct and pointer to a struct. Using the reference is more
efficient since it doe snot have to copy the whole struct.

Also change some structs to use he actual type from the template instead
of some nested one to make sure it has to correct fields.

shell completion --format: work with nil structs
AutocompleteFormat() takes the format struct as argument. Often the structs
are deeply nested and contain other structs. Up until now if there was a
pointer to a struct the logic was not able to get the field names from
that, simply because the pointer was nil. However it is possible to
create a new initialized type with reflect.New(). This allows us to
complete all struct fields/functions even when there nil pointers.
Therefore we can drop the extra initialization which was done by some
callers.

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.

Remove error stutter
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 system df: fix percent calculation
The calculate the percentage we need floating point numbers. The current
code however casted the result of reclaimable/size to an int first.
Casting to an int in go will just discard the decimal points, thus the
result was either 0 or 1 so if multiplied by 100 it would show up as 0%
or 100%.

To fix this we have to multiply by 100 first before casting the result
to an int. Also add a check for div by zero which results in NaN and use
math.Round() to correctly round a number.

system prune: remove all networks
podman system prune should also remove all networks. When we want to
users to migrate to the new network stack we recommend to run podman
system reset. However this did not remove networks and if there were
still networks around we would continue to use cni since this was
considered an old system.

There is one exception for the default network. It should not be removed
since this could cause other issues when it no longer exists. The
network backend detection logic ignores the default network so this is
fine.

In case the command inside the podman unshare env failed podman unshare
always exits with 125 and prints `Error: exit status 125`. This is a
bad user experience and makes it difficult to use in scripts which could
expect certain exit codes.
This commit makes sure podman unshare uses the same exit code as the
command and does not print the useless `exit status X` message.

Also to match podman run/exec it should return 126 for EPERM

podman service reaper
Add a new service reaper package. Podman currently does not reap all
child processes. The slirp4netns and rootlesskit processes are not
reaped. The is not a problem for local podman since the podman process
dies before the other processes and then init will reap them for us.

However with podman system service it is possible that the podman
process is still alive after slirp died. In this case podman has to reap
it or the slirp process will be a zombie until the service is stopped.

The service reaper will listen in an extra goroutine on SIGCHLD. Once it
receives this signal it will try to reap all pids that were added with
`AddPID()`. While I would like to just reap all children this is not
possible because many parts of the code use `os/exec` with `cmd.Wait()`.
If we reap before `cmd.Wait()` things can break, so reaping everything
is not an option.
