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

Improve our compatibility with Docker by better handling the
state strings that we print in `podman ps`. Docker capitalizes
all states in `ps` (we do not) - fix this in our PS code. Also,
stop normalizing ContainerStateConfigured to the "Created" state,
and instead make it always be Created, with the existing Created
state becoming Initialized.
I didn't rename the actual states because I'm somewhat reticent
to make such a large change a day before we leave for break. It's
somewhat confusing that ContainerStateConfigured now returns
Created, but internally and externally we're still consistent.
[NO NEW TESTS NEEDED] existing tests should catch anything that
broke.
I also consider this a breaking change. I will flag appropriately
on Github.

CRIU's pre-copy migration support relies on the soft dirty page tracking
in the Linux kernel:
https://www.kernel.org/doc/Documentation/vm/soft-dirty.txt
This functionality is not implemented for all architectures and it can
also be turned off in the kernel.
CRIU can check if the combination of architecture/kernel/CRIU supports
the soft dirty page tracking and exports this feature checking
functionality in go-criu.
This commit adds an early check if the user selects pre-copy
checkpointing to error out if the system does not support it.

Rework the --network parse logic to support multiple networks with
specific network configuration settings.
--network can now be set multiple times. For bridge network mode the
following options have been added:
- **alias=name**: Add network-scoped alias for the container.
- **ip=IPv4**: Specify a static ipv4 address for this container.
- **ip=IPv6**: Specify a static ipv6 address for this container.
- **mac=MAC**: Specify a static mac address address for this container.
- **interface_name**: Specify a name for the created network interface inside the container.
So now you can set --network bridge:ip=10.88.0.10,mac=44:33:22:11:00:99
for the default bridge network as well as for network names.
This is better than using --ip because we can set the ip per network
without any confusion which network the ip address should be assigned
to.
The --ip, --mac-address and --network-alias options are still supported
but --ip or --mac-address can only be set when only one network is set.
This limitation already existed previously.
The ability to specify a custom network interface name is new

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",

"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

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.

InfraContainer should go through the same creation process as regular containers. This change was from the cmd level
down, involving new container CLI opts and specgen creating functions. What now happens is that both container and pod
cli options are populated in cmd and used to create a podSpecgen and a containerSpecgen. The process then goes as follows
FillOutSpecGen (infra) -> MapSpec (podOpts -> infraOpts) -> PodCreate -> MakePod -> createPodOptions -> NewPod -> CompleteSpec (infra) -> MakeContainer -> NewContainer -> newContainer -> AddInfra (to pod state)
