Charlie Doern 842c6c7c67 podman generate spec
implement a new command `podman generate spec` which can formulate a json specgen to be consumed by both the pod
and container creation API.

supported flags are

--verbose (default true) print output to the terminal
--compact print the json output in a single line format to be piped to the API
--filename put the output in a file
--clone rename the pod/ctr in the spec so it won't conflict w/ an existing entity

added the following flags and handling for podman pod create

--memory-swap
--cpuset-mems
--device-read-bps
--device-write-bps
--blkio-weight
--blkio-weight-device
--cpu-shares

given the new backend for systemd in c/common, all of these can now be exposed to pod create.

as well!

specgen,run: support running container from valid manifest list
Following PR adds support for running containers from a manifest list
present on localstorage. Before this PR podman only supports running
containers from valid images but not from manifest list.

So `podman run -it --platform <some> <manifest-list> command` should
become functional now and users should be able to resolve images on the
bases of provided `--platform` string.

Example
```
podman manifest create test
podman build --platform linux/amd64,linux/arm64 --manifest test .
podman run --rm --platform linux/arm64/v8 test uname -a
```

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.

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

Brent Baude 2a524fcaec fix healthcheck timeouts and ut8 coercion
this commit fixes two bugs and adds regression tests.

when getting healthcheck values from an image, if the image does not
have a timeout defined, this resulted in a 0 value for timeout.  The
default as described in the man pages is 30s.

when inspecting a container with a healthcheck command, a customer
observed that the &, <, and > characters were being converted into a
unicode escape value.  It turns out json marshalling will by default
coerce string values to ut8.

Vendor the latest HEAD in c/common to pull in changes for a faster
inspection of images.  Previously, only the size computation was

In many cases, the parent image is not needed but it takes around 10ms
on my local machine.  With this change, we cut off 10ms from many code
paths, most importantly, container creation.

Brent Baude 3c3fa6fac4 implement init containers in podman
this is the first pass at implementing init containers for podman pods.
init containersare made popular by k8s as a way to run setup for pods
before the pods standard containers run.

unlike k8s, we support two styles of init containers: always and
oneshot.  always means the container stays in the pod and starts
whenever a pod is started.  this does not apply to pods restarting.
oneshot means the container runs onetime when the pod starts and then is
removed.

Valentin Rothberg 5fc622f945 create: support images with invalid platform
Much to my regret, there is a number of images in the wild with invalid
platforms breaking the platform checks in libimage that want to make
sure that a local image is matching the expected platform.

Imagine a `podman run --arch=arm64 fedora` with a local amd64 fedora
image.  We really shouldn't use the local one in this case and pull down
the arm64 one.

The strict platform checks in libimage in combination with invalid
platforms in images surfaced in Podman being able to pull an image but
failing to look it up in subsequent presence checks.  A `podman run`
would hence pull such an image but fail to create the container.

Support images with invalid platforms by vendoring the latest HEAD from
containers/common.  Also remove the partially implemented pull-policy
logic from Podman and let libimage handle that entirely.  However,
whenever --arch, --os or --platform are specified, the pull policy will
be forced to "newer".  This way, we pessimistically assume that the
local image has an invalid platform and we reach out to the registry.
If there's a newer image (i.e., one with a different digest), we'll pull
it down.

Please note that most of the logic has either already been implemented
in libimage or been moved down which allows for removing some clutter
from Podman.

[NO TESTS NEEDED] since c/common has new tests.  Podman can rely on the
existing tests.

Valentin Rothberg 0f7d54b026 migrate Podman to containers/common/libimage
Migrate the Podman code base over to `common/libimage` which replaces
`libpod/image` and a lot of glue code entirely.

Note that I tried to leave bread crumbs for changed tests.

Miscellaneous changes:

 * Some errors yield different messages which required to alter some
   tests.

 * I fixed some pre-existing issues in the code.  Others were marked as
   `//TODO`s to prevent the PR from exploding.

 * The `NamesHistory` of an image is returned as is from the storage.
   Previously, we did some filtering which I think is undesirable.
   Instead we should return the data as stored in the storage.

 * Touched handlers use the ABI interfaces where possible.

 * Local image resolution: previously Podman would match "foo" on
   "myfoo".  This behaviour has been changed and Podman will now
   only match on repository boundaries such that "foo" would match
   "my/foo" but not "myfoo".  I consider the old behaviour to be a
   bug, at the very least an exotic corner case.

 * Futhermore, "foo:none" does *not* resolve to a local image "foo"
   without tag anymore.  It's a hill I am (almost) willing to die on.

 * `image prune` prints the IDs of pruned images.  Previously, in some
   cases, the names were printed instead.  The API clearly states ID,
   so we should stick to it.

 * Compat endpoint image removal with _force_ deletes the entire not
   only the specified tag.

Valentin Rothberg 0f668aa085 workdir presence checks
A container's workdir can be specified via the CLI via `--workdir` and
via an image config with the CLI having precedence.

Since images have a tendency to specify workdirs without necessarily
shipping the paths with the root FS, make sure that Podman creates the
workdir.  When specified via the CLI, do not create the path, but check
for its existence and return a human-friendly error.

NOTE: `crun` is performing a similar check that would yield exit code
127.  With this change, however, Podman performs the check and yields
exit code 126.  Since this is specific to `crun`, I do not consider it
to be a breaking change of Podman.
