Basic theory: We remove the container, but *only from the DB*.
We leave it in c/storage, we leave the lock allocated, we leave
it running (if it is). Then we create an identical container with
an altered name, and add that back to the database. Theoretically
we now have a renamed container.
The advantage of this approach is that it doesn't just apply to
rename - we can use this to make *any* configuration change to a
container that does not alter its container ID.
Potential problems are numerous. This process is *THOROUGHLY*
non-atomic at present - if you `kill -9` Podman mid-rename things
will be in a bad place, for example. Also, we can't rename
containers that can't be removed normally - IE, containers with
dependencies (pod infra containers, for example).
The largest potential improvement will be to move the majority of
the work into the DB, with a `RecreateContainer()` method - that
will add atomicity, and let us remove the container without
worrying about depencies and similar issues.
Potential problems: long-running processes that edit the DB and
may have an older version of the configuration around. Most
notable example is `podman run --rm` - the removal command needed
to be manually edited to avoid this one. This begins to get at
the heart of me not wanting to do this in the first place...
This provides CLI and API implementations for frontend, but no
tunnel implementation. It will be added in a future release (just
held back for time now - we need this in 3.0 and are running low
on time).
This is honestly kind of horrifying, but I think it will work.

Although storage is more human-readable when expressed in SI units,
IEC/JEDEC (Bytes) units are more pertinent for memory-related values
(and match the format of the --memory* command-line options).
(To prevent possible compatibility issues, the default SI display is
left unchanged)

In 2.2.x, we moved `play kube` to use the Start() API for pods,
which reported errors in a different way (all containers are
started in parallel, and then results reported as a block). The
migration attempted to preserve compatibility by returning only
one error, but that's not really a viable option as it can
obscure the real reason that a pod is failing. Further, the code
was not correctly handling the API's errors - Pod Start() will,
on any container error, return a map of container ID to error
populated for all container errors *and* return ErrPodPartialFail
for overall error - the existing code did not handle the partial
failure error and thus would never return container errors.
Refactor the `play kube` API to include a set of errors for
containers in each pod, so we can return all errors that occurred
to the frontend and print them for the user, and correct the
backend code so container errors are actually forwarded.

When migrating a container with associated volumes, the content of
these volumes should be made available on the destination machine.
This patch enables container checkpoint/restore with named volumes
by including the content of volumes in checkpoint file. On restore,
volumes associated with container are created and their content is
restored.
The --ignore-volumes option is introduced to disable this feature.
Example:
# podman container checkpoint --export checkpoint.tar.gz <container>
The content of all volumes associated with the container are included
in `checkpoint.tar.gz`
# podman container checkpoint --export checkpoint.tar.gz --ignore-volumes <container>
The content of volumes is not included in `checkpoint.tar.gz`. This is
useful, for example, when the checkpoint/restore is performed on the
same machine.
# podman container restore --import checkpoint.tar.gz
The associated volumes will be created and their content will be
restored. Podman will exit with an error if volumes with the same
name already exist on the system or the content of volumes is not
included in checkpoint.tar.gz
# podman container restore --ignore-volumes --import checkpoint.tar.gz
Volumes associated with container must already exist. Podman will not
create them or restore their content.

This change adds code to report the reclaimed space after a prune.
Reclaimed space from volumes, images, and containers is recorded
during the prune call in a PruneReport struct. These structs are
collected into a slice during a system prune and processed afterwards
to calculate the total reclaimed space.

There exists a unit test to ensure that shell completion functions are
defined. However there was no check about the quality of the provided
shell completions. Lets change that.
The idea is to create a general test that makes sure we are suggesting
containers,pods,images... for the correct commands. This works by
reading the command use line and checking for each arg if we provide
the correct suggestions for this arg.
It includes the following tests:
- flag suggestions if [options] is set
- container, pod, image, network, volume, registry completion
- path completion for the appropriate arg KEYWORDS (`PATH`,`CONTEXT`,etc.)
- no completion if there are no args
- completion for more than one arg if it ends with `...]`
The test does not cover completion values for flags and not every arg KEYWORD
is supported. This is still a huge improvement and covers most use cases.
This test spotted several inconsistencies between the completion and the
command use line. All of them have been adjusted to make the test pass.
The biggest advantage is that the completions always match the latest
command changes. So if someone changes the arguments for a command this
ensures that the completions must be adjusted.
