Problem: the system test 'is()' checker was poorly thought out.
For example, there is no way to check for inequality or for
absence of a substring.
Solution, step 1: introduce new assert(), copied almost verbatim
from buildah, where it has been successful in addressing the
gaps in is().
The logical next step is to search the tests for 'die' and
for 'run', looking for negative assertions which we can
replace with assert(). There were a lot, and in the process
I found a number of ugly bugs in the tests themselves. I've
taken the liberty of fixing these.
Important note: at this time we have both assert() and is().
Replacing all instances of is() would be impossible to review.

This is the script I've been using (and tweaking) for the past
two weeks. It's ready for general review and use, with the
proviso that there are still corner cases I haven't tested.

The patch introduces the following test cases:
1. An attempt to checkpoint a container that does not exist should fail.
2. Checkpoint of a running container with --create-image should create a
checkpoint image.
3. A single checkpoint image can be used to restore multiple containers,
each with a different name.
4. Restoring multiple containers from checkpoint images with a single
restore command.

This is an enhancement proposal for the checkpoint / restore feature of
Podman that enables container migration across multiple systems with
standard image distribution infrastructure.
A new option `--create-image <image>` has been added to the
`podman container checkpoint` command. This option tells Podman to
create a container image. This is a standard image with a single layer,
tar archive, that that contains all checkpoint files. This is similar to
the current approach with checkpoint `--export`/`--import`.
This image can be pushed to a container registry and pulled on a
different system. It can also be exported locally with `podman image
save` and inspected with `podman inspect`. Inspecting the image would
display additional information about the host and the versions of
Podman, criu, crun/runc, kernel, etc.
`podman container restore` has also been extended to support image
name or ID as input.

We already have ipv6 enabled as default via the containers.conf setting.
However the documentation did not reflect this. Also if no options were
set in contianers.conf it would have ipv6 disabled.
We can now remove the extra option from containers.conf.
Also fix another outdated option description for host.containers.internal
and add that the options can also be set in contianers.conf.

Add a proof of concept for benchmarking Podman. The benchmarks are
implemented by means of the end-to-end test suite but hidden behind
a `benchmarks` build tag. Running `make localbenchmarks` will run
`test/e2e` with the specific build tag and set ginkgo's "focus" to
the specific "Podman Benchmark Suite" to only run this spec and skip
all others.
ginkgo will print a report before terminating listing the CPU and memory
stats for each benchmark. New benchmarks can easily be added via the
`newBenchmark` function that also supports adding an `init()` function
to each benchmark which allows for performing certain setups for the
specific benchmark. For instance, benchmarking `podman start` requires
creating a container beforehand.
Podman may be called more than once in the main function of a benchmark
but note that the displayed memory consumption is then a sum of all
Podman invocations. The memory consumption is collected via
`/usr/bin/time`.
A benchmark's report is split into CPU and memory as displayed below:
```
[CPU] podman images:
Fastest Time: 0.146s
Slowest Time: 0.187s
Average Time: 0.180s ± 0.015s
[MEM] podman images:
Smallest: 41892.0KB
Largest: 42792.0KB
Average: 42380.7KB ± 286.4KB
```
Note that the benchmarks are not wired into the CI yet. They are meant
as a proof of concept. More benchmarks and the plumbing into CI will
happen in a later change.

The podman machine ls command would benefit from a --quiet flag which
would only print the machine names without the extra information. It
also implies --noheader as well. This can be helpful for scripting with
the podman cli.

@nalind found a proper fix in c/storage [1] to address the performance
issue. So we really don't need the flag anymore. Note the flag has
never made it into any release.

--tail=1 is not working f you restart a container with journald logging.
We see the exit status and then call into the logging a second time
causing all of the logs to print.
Removing the tail log on exited seems to fix the problem.
