6d6bdabc8c healthcheck: stop showing wrong status when --no-healthcheck is set
Containers started with `--no-healthcheck` are configured to contain no
healthcheck and test configured as `NONE`. Podman shows wrong status as
such use cases.

Following commit fixes the faulty behavior of stauts field for
containers started with `--no-healthcheck`

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

resolves #10875

80e56fa12b Added optional container restore statistics
This adds the parameter '--print-stats' to 'podman container restore'.
With '--print-stats' Podman will measure how long Podman itself, the OCI
runtime and CRIU requires to restore a checkpoint and print out these
information. CRIU already creates process restore statistics which are
just read in addition to the added measurements. In contrast to just
printing out the ID of the restored container, Podman will now print
out JSON:

 # podman container restore --latest --print-stats
 {
     "podman_restore_duration": 305871,
     "container_statistics": [
         {
             "Id": "47b02e1d474b5d5fe917825e91ac653efa757c91e5a81a368d771a78f6b5ed20",
             "runtime_restore_duration": 140614,
             "criu_statistics": {
                 "forking_time": 5,
                 "restore_time": 67672,
                 "pages_restored": 14
             }
         }
     ]
 }

The output contains 'podman_restore_duration' which contains the
number of microseconds Podman required to restore the checkpoint. The
output also includes 'runtime_restore_duration' which is the time
the runtime needed to restore that specific container. Each container
also includes 'criu_statistics' which displays the timing information
collected by CRIU.

0136a66a83 libpod: deduplicate ports in db
The OCICNI port format has one big problem: It does not support ranges.
So if a users forwards a range of 1k ports with podman run -p 1001-2000
we have to store each of the thousand ports individually as array element.
This bloats the db and makes the JSON encoding and decoding much slower.
In many places we already use a better port struct type which supports
ranges, e.g. `pkg/specgen` or the new network interface.

Because of this we have to do many runtime conversions between the two
port formats. If everything uses the new format we can skip the runtime
conversions.

This commit adds logic to replace all occurrences of the old format
with the new one. The database will automatically migrate the ports
to new format when the container config is read for the first time
after the update.

The `ParsePortMapping` function is `pkg/specgen/generate` has been
reworked to better work with the new format. The new logic is able
to deduplicate the given ports. This is necessary the ensure we
store them efficiently in the DB. The new code should also be more
performant than the old one.

To prove that the code is fast enough I added go benchmarks. Parsing
1 million ports took less than 0.5 seconds on my laptop.

Benchmark normalize PortMappings in specgen:
Please note that the 1 million ports are actually 20x 50k ranges
because we cannot have bigger ranges than 65535 ports.

bf8fd943ef Allow 'container restore' with '--ipc host'
Trying to restore a container that was started with '--ipc host' fails
with:

Error: error creating container storage: ProcessLabel and Mountlabel must either not be specified or both specified

We already fixed this exact same error message for containers started

container is a privileged container (c.config.Privileged). Unfortunately
this does not work for containers started with '--ipc host'.

This commit changes the check for a privileged container to check if
both the ProcessLabel and the MountLabel is actually set and only then
re-uses those labels.

85e8fbf7f3 Wire network interface into libpod
Make use of the new network interface in libpod.

This commit contains several breaking changes:
- podman network create only outputs the new network name and not file
  path.
- podman network ls shows the network driver instead of the cni version
  and plugins.
- podman network inspect outputs the new network struct and not the cni
  conflist.
- The bindings and libpod api endpoints have been changed to use the new
  network structure.

The container network status is stored in a new field in the state. The
status should be received with the new `c.getNetworkStatus`. This will
migrate the old status to the new format. Therefore old containers should
contine to work correctly in all cases even when network connect/
disconnect is used.

New features:
- podman network reload keeps the ip and mac for more than one network.
- podman container restore keeps the ip and mac for more than one
  network.
- The network create compat endpoint can now use more than one ipam
  config.

The man pages and the swagger doc are updated to reflect the latest
changes.

985c717085 Fix handling of user specified container labels
Currently we override the SELinux labels specified by the user
if the container is runing a kata container or systemd container.

This PR fixes to use the label specified by the user.

db2f474284 Drop podman create --storage-opt container flag
The global flag will work in either location, and this flag just breaks
users expectations, and is basically a noop.

Also fix global storage-opt so that podman-remote can use it.

[NO TESTS NEEDED] Since it would be difficult to test in ci/cd.

9db534e53a [NO TESTS NEEDED] Create /etc/mtab with the correct ownership
Create the /etc and /etc/mtab directories with the
correct ownership based on what the UID and GID is
for the container. This was causing issue when starting
the infra container with userns as the /etc directory
wasn't being created with the correct ownership.

240bbc3bfa Fix pre-checkpointing
Unfortunately --pre-checkpointing never worked as intended and recent
changes to runc have shown that it is broken.

To create a pre-checkpoint CRIU expects the paths between the
pre-checkpoints to be a relative path. If having a previous checkpoint
it needs the be referenced like this: --prev-images-dir ../parent

Unfortunately Podman was giving runc (and CRIU) an absolute path.

Unfortunately, again, until March 2021 CRIU silently ignored if
the path was not relative and switch back to normal checkpointing.

This has been now fixed in CRIU and runc and running pre-checkpoint
with the latest runc fails, because runc already sees that the path is
absolute and returns an error.

This commit fixes this by giving runc a relative path.

This commit also fixes a second pre-checkpointing error which was just
recently introduced.

So summarizing: pre-checkpointing never worked correctly because CRIU
ignored wrong parameters and recent changes broke it even more.

Now both errors should be fixed.

b75bb4665e Create the /etc/mtab file if does not exists
We should create the /etc/mtab->/proc/mountinfo link
so that mount command will work within the container.

Docker does this by default.

30544f225e fix restart always with slirp4netns
When a container is automatically restarted due its restart policy and
the container used the slirp4netns netmode, the slirp4netns process
died. This caused the container to lose network connectivity.

To fix this we have to start a new slirp4netns process.
