Red Hat registry is too unreliable. (As of this writing
in January 2023, quay.io is not much better, but this is
a new flake. Ubi has been flaking for a year or more).
Instead of UBI, use the new systemd-image added to system tests
in #16814. Since this reduces the number of cached images,
a few unrelated tests (image count) need to be tweaked.
And, sigh, Fedora systemd colorizes boot messages by default,
causing a failure where we don't see an expected Reached Target
message. I don't want to rely on ASCII formatting codes, so
I've updated the build-systemd-image script so it disables
systemd colors, and have built a new systemd-image:20230106.
Made a few small usability improvements to the script as well.
Closes: #16695

Package `io/ioutil` was deprecated in golang 1.16, preventing podman from
building under Fedora 37. Fortunately, functionality identical
replacements are provided by the packages `io` and `os`. Replace all
usage of all `io/ioutil` symbols with appropriate substitutions
according to the golang docs.

`os.ReadDir` was added in Go 1.16 as part of the deprecation of `ioutil`
package. It is a more efficient implementation than `ioutil.ReadDir`.

A number of standard image names were lower-case, leading to
confusion in code such as:
registry := podman(... , "-n", "registry", registry, ...)
^--- variable ^---- constant
Fix a number of those to be capitalized and with _IMAGE suffix:
registry := podman(..., REGISTRY_IMAGE

Polish the push and pull benchmarks. In particular, make sure to not be
network bound during these benchmarks by running a local registry and
pushing a local image that can later on be pulled.

The errcheck linter makes sure that errors are always check and not
ignored by accident. It spotted a lot of unchecked errors, mostly in the
tests but also some real problem in the code.

Add more benchmarks for the most common and performance-critical image
commands. Benchmarks for `podman build` should go into a separate
section.

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.
