We now use the golang error wrapping format specifier `%w` instead of
the deprecated github.com/pkg/errors package.

Forward the ssh exit code to the podman caller. This is useful for
scripts. Use the same logic as podman unshare.

Since we want to use the rootless cni ns also for netavark we should
pick a more generic name. The name is now "rootless network namespace"
or short "rootless netns".
The rename might cause some issues after the update but when the
all containers are restarted or the host is rebooted it should work
correctly.

In case the command inside the podman unshare env failed podman unshare
always exits with 125 and prints `Error: exit status 125`. This is a
bad user experience and makes it difficult to use in scripts which could
expect certain exit codes.
This commit makes sure podman unshare uses the same exit code as the
command and does not print the useless `exit status X` message.
Also to match podman run/exec it should return 126 for EPERM
and 127 for ENOENT.

[NO TESTS NEEDED]
This commit cleans up two issues:
* Most commands support all EngineModes so default to that. Let
outlayers declare their intent.
* Use cobra.Annotations to set supported EngineMode. This simplies
instantiating commands as there is now one method to communicate a
commands requirements rather than two.
* Combined aliased commands into one file
* Fixed aliased commands where Args field did not match
* Updated examples in README.md for writing commands
* Remove redundant flag DisableFlagsInUseLine in cobra.Command
initialization.

Add a new --rootless-cni option to podman unshare to also join the
rootless-cni network namespace. This is useful if you want to connect
to a rootless container via IP address. This is only possible from the
rootless-cni namespace and not from the host namespace. This option also
helps to debug problems in the rootless-cni namespace.

We missed bumping the go module, so let's do it now :)
* Automated go code with github.com/sirkon/go-imports-rename
* Manually via `vgrep podman/v2` the rest

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.

Allow automatic generation for shell completion scripts
with the internal cobra functions (requires v1.0.0+).
This should replace the handwritten completion scripts
and even adds support for fish. With this approach it is
less likley that completions and code are out of sync.
We can now create the scripts with
- podman completion bash
- podman completion zsh
- podman completion fish
To test the completion run:
source <(podman completion bash)
The same works for podman-remote and podman --remote and
it will complete your remote containers/images with
the correct endpoints values from --url/--connection.
The completion logic is written in go and provided by the
cobra library. The completion functions lives in
`cmd/podman/completion/completion.go`.
The unit test at cmd/podman/shell_completion_test.go checks
if each command and flag has an autocompletion function set.
This prevents that commands and flags have no shell completion set.
This commit does not replace the current autocompletion scripts.
Closes#6440

With the advent of Podman 2.0.0 we crossed the magical barrier of go
modules. While we were able to continue importing all packages inside
of the project, the project could not be vendored anymore from the
outside.
Move the go module to new major version and change all imports to
`github.com/containers/libpod/v2`. The renaming of the imports
was done via `gomove` [1].

New functionality in hack/man-page-checker: start cross-
referencing the man page 'Synopsis' line against the
output of 'podman foo --help'. This is part 1, flag/option
consistency. Part 2 (arg consistency) is too big and will
have to wait for later.
flag/option consistency means: if 'podman foo --help'
includes the string '[flags]' in the Usage message,
make sure the man page includes '[*options*]' in its
Synopsis line, and vice-versa. This found several
inconsistencies, which I've fixed.
While doing this I realized that Cobra automatically
includes a 'Flags:' subsection in its --help output
for all subcommands that have defined flags. This
is great - it lets us cross-check against the
usage synopsis, and make sure that '[flags]' is
present or absent as needed, without fear of
human screwups. If a flag-less subcommand ever
gets extended with flags, but the developer forgets
to add '[flags]' and remove DisableFlagsInUseLine,
we now have a test that will catch that. (This,
too, caught two instances which I fixed).
I don't actually know if the new man-page-checker
functionality will work in CI: I vaguely recall that
it might run before 'make podman' does; and also
vaguely recall that some steps were taken to remedy
that.

...plus a few others. And fixes to actual parsing.
If a command's usage message includes '...' in the
argument list, assume it can take unlimited arguments.
Nothing we can check.
For all others, though, the ALL-CAPS part on the
right-hand side of the usage message will define
an upper bound on the number of arguments accepted
by the command. So in our 'podman --help' test,
generate N+1 args and run that command. We expect
a 125 exit status and a suitably helpful error message.
Not all podman commands or subcommands were checking,
so I fixed that. And, fixed some broken usage messages
(all-caps FLAGS, and '[flags]' at the end of 'ARGS').
Add new checks to the help test to prevent those in
the future.
Plus a little refactoring/cleanup where necessary.
