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.

This reverts commit e133a06d2f.
@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.

For better docker compatibility we should use the bridge network mode as
default for rootless. This was already done previously but commit
535818414c introduced this regression in v4.0.
Since the apiv2 test are only run rootful we cannot catch this problem
in CI.

When you run podman-remote unsahre for example you currently get:
Error: unrecognized command `podman-remote unshare`
This is because we do not add the command to the cobra tree when we run
in remote mode. However this is a bad user experience since it is not
clear that the command is only supported for local podman. Users are
left wondering why this does not work and could think the documentation
is wrong.
To fix it we add a clear error message:
Error: cannot use command "podman-remote unshare" with the remote podman client

Since netavark does not support dhcp yet we have to create a macvlan
network with a static subnet. Since we do not use the network to run
containers the actual subnet does not matter.
Also stop hard coding the network id. Unlike the cni backend the
netavark backend creates random ids that are not predictable.
