Only process the incoming args[] (which is a single-element array
for some reason) once, and use a semantic variable name for the value
we care about.
Should not change behavior, the only caller already supposedly ensures
that len(args) == 1.

This bug is reproduced when we execute the following command:
1. podman manifest add <manifest list> <images exist on local storage>
2. podman manifest push --rm <manifest list> dir:<directory>
If pushing succeeds, it is expected to remove only a manifest list.
However, manifest list remains on local storage and images are removed.
This commit fixes `podman manifest push --rm` to remove only a manifest list.
And, supports `manifest push --rm option` in remote environment,
like host environment.

- Allow creating sigstore signatures via --sign-by-sigstore-private-key .
Like existing --sign-by, it does not work remote (in this case
because we would have to copy the private key to the server).
- Allow passing a passphrase (which is mandatory for sigstore private keys)
via --sign-passphrase-file; if it is not provided, prompt interactively.
- Also, use that passphrase for --sign-by as well, allowing non-interactive
GPG use. (But --sign-passphrase-file can only be used with _one of_
--sign-by and --sign-by-sigstore-private-key.)
Note that unlike the existing code, (podman build) does not yet
implement sigstore (I'm not sure why it needs to, it seems not to
push images?) because Buildah does not expose the feature yet.
Also, (podman image sign) was not extended to support sigstore.
The test for this follows existing (podman image sign) tests
and doesn't work rootless; that could be improved by exposing
a registries.d override option.
The test for push is getting large; I didn't want to
start yet another registry container, but that would be an
alternative. In the future, Ginkgo's Ordered/BeforeAll
would allow starting a registry once and using it for two
tests.

`podman-remote push` has shown absolutely no progress at all. Fix that
by doing essentially the same as the remote-pull code does.
The get-free-out-of-jail-card for backwards compatibility is to let the
`quiet` parameter default to true. Since the --quioet flag wasn't
working before either, older Podman clients do not set it.
Also add regression tests to make sure we won't regress again.

There is a possibility that podman does not output expected error message.
(e.g. When pause rootless cgroups v1 container on host)
This problem is solved by appending `report.Errs` to `reports` before `continue`.

add support for podman-remote image scp as well as direct access via the API. This entailed
a full rework of the layering of image scp functions as well as the usual API plugging and type creation
also, implemented podman image scp tagging. which makes the syntax much more readable and allows users t tag the new image
they are loading to the local/remote machine:
allow users to pass a "new name" for the image they are transferring
`podman tag` as implemented creates a new image im `image list` when tagging, so this does the same
meaning that when transferring images with tags, podman on the remote machine/user will load two images
ex: `podman image scp computer1::alpine computer2::foobar` creates alpine:latest and localhost/foobar on the remote host
implementing tags means removal of the flexible syntax. In the currently released podman image scp, the user can either specify
`podman image scp source::img dest::` or `podman image scp dest:: source::img`. However, with tags this task becomes really hard to check
which is the image (src) and which is the new tag (dst). Removal of that streamlines the arg parsing process

add podman volume reload to sync volume plugins

Libpod requires that all volumes are stored in the libpod db. Because
volume plugins can be created outside of podman, it will not show all
available plugins. This podman volume reload command allows users to
sync the libpod db with their external volume plugins. All new volumes
from the plugin are also created in the libpod db and when a volume from
the db no longer exists it will be removed if possible.
There are some problems:
- naming conflicts, in this case we only use the first volume we found.
This is not deterministic.
- race conditions, we have no control over the volume plugins. It is
possible that the volumes changed while we run this command.

This commit addresses three intertwined bugs to fix an issue when using
Gitlab runner on Podman. The three bug fixes are not split into
separate commits as tests won't pass otherwise; avoidable noise when
bisecting future issues.
1) Podman conflated states: even when asking to wait for the `exited`
state, Podman returned as soon as a container transitioned to
`stopped`. The issues surfaced in Gitlab tests to fail [1] as
`conmon`'s buffers have not (yet) been emptied when attaching to a
container right after a wait. The race window was extremely narrow,
and I only managed to reproduce with the Gitlab runner [1] unit
tests.
2) The clearer separation between `exited` and `stopped` revealed a race
condition predating the changes. If a container is configured for
autoremoval (e.g., via `run --rm`), the "run" process competes with
the "cleanup" process running in the background. The window of the
race condition was sufficiently large that the "cleanup" process has
already removed the container and storage before the "run" process
could read the exit code and hence waited indefinitely.
Address the exit-code race condition by recording exit codes in the
main libpod database. Exit codes can now be read from a database.
When waiting for a container to exit, Podman first waits for the
container to transition to `exited` and will then query the database
for its exit code. Outdated exit codes are pruned during cleanup
(i.e., non-performance critical) and when refreshing the database
after a reboot. An exit code is considered outdated when it is older
than 5 minutes.
While the race condition predates this change, the waiting process
has apparently always been fast enough in catching the exit code due
to issue 1): `exited` and `stopped` were conflated. The waiting
process hence caught the exit code after the container transitioned
to `stopped` but before it `exited` and got removed.
3) With 1) and 2), Podman is now waiting for a container to properly
transition to the `exited` state. Some tests did not pass after 1)
and 2) which revealed the third bug: `conmon` was executed with its
working directory pointing to the OCI runtime bundle of the
container. The changed working directory broke resolving relative
paths in the "cleanup" process. The "cleanup" process error'ed
before actually cleaning up the container and waiting "main" process
ran indefinitely - or until hitting a timeout. Fix the issue by
executing `conmon` with the same working directory as Podman.
Note that fixing 3) *may* address a number of issues we have seen in the
past where for *some* reason cleanup processes did not fire.
