networking: lookup child IP in networks
if a CNI network is added to the container, use the IP address in that
network instead of hard-coding the slirp4netns default.

commit 5e65f0ba30 introduced this
regression.

rootlessport: set source IP to slirp4netns device

using rootlesskit.

Matthew Heon b0286d6b43 Implement pod-network-reload
This adds a new command, 'podman network reload', to reload the
networks of existing containers, forcing recreation of firewall
rules after e.g. `firewall-cmd --reload` wipes them out.

Under the hood, this works by calling CNI to tear down the
existing network, then recreate it using identical settings. We
request that CNI preserve the old IP and MAC address in most
cases (where the container only had 1 IP/MAC), but there will be
some downtime inherent to the teardown/bring-up approach. The
architecture of CNI doesn't really make doing this without
downtime easy (or maybe even possible...).

At present, this only works for root Podman, and only locally.
I don't think there is much of a point to adding remote support
(this is very much a local debugging command), but I think adding
rootless support (to kill/recreate slirp4netns) could be
valuable.

Ed Santiago 1646da834c System test additions
- run --userns=keep-id: confirm that $HOME gets set (#8013)

 - inspect: confirm that JSON output is a sane number of
   lines (10 or more), not an unreadable one-liner (#8011
   and #8021). Do so with image, pod, network, volume
   because the code paths might be different.

 - cgroups: confirm that 'run' preserves cgroup manager (#7970)

 - sdnotify: reenable tests, and hope CI doesn't hang. This
   test was disabled on August 18 because CI jobs were hanging
   and timing out. My suspicion was that it was #7316, which
   in turn seems to have hinged on conmon #182. The latter
   was merged on Sep 16, so let's cross our fingers and see
   what happens.

Also: remove inaccurate warning from a networking test.

And, wow, fix is_cgroupsv2(), it has never actually worked.

Ed Santiago d380ba0394 logformatter: add Synopsis at top of each page
At the top of each generated page, add a Synopsis table with:

  PR number/name, and link to github
  Author name(s)
  Test name (fedora/ubuntu, rootless, etc)
  Cirrus build ID (usually uninteresting)
  Cirrus task ID (usu. important), with link to Cirrus
  The value of $SPECIALMODE

This is all we can get from the Cirrus environment in
which logformatter runs; we can't get things like
cgroup manager or username that the test runs under.

Note that the table is at the top, which is usually
unseen because we autoscroll to the bottom on
page load. I tentatively think that top is a more
natural place for this info than bottom, but am
willing to listen to arguments against.

Also, one minor tweak: highlight podman commands in
the BATS output. The idea is to make it easier for the eye
to spot those, then copy/paste them to find a reproducer.

And, sigh, disable the new 'podman network create'
system test. It is flaking much too much.

Fix handling of remove of bogus volumes, networks and Pods
In podman containers rm and podman images rm, the commands
exit with error code 1 if the object does not exists.

This PR implements similar functionality to volumes, networks, and Pods.

Similarly if volumes or Networks are in use by other containers, and return
exit code 2.

Ed Santiago bd3c66fc81 system tests: new tests
- podman network create: new test

- podman pull by-sha + podman images -a (#7651)

- podman image mount: new test

- podman pod: --infra-image and --infra-command (#7167)

For convenience and robustness, build a new testimage
containing a custom file /home/podman/testimage-id
with contents YYYYMMDD (same as image tag). The
image-mount test checks that this file exists and
has the desired content. New testimage also includes
a dummy 'pause' executable, for testing pod infra.

Updates from testimage:20200902 to :20200917

Ed Santiago a9dbd2b3de Migrate away from docker.io
CI and system tests currently pull some images from docker.io.
Eliminate that, by:

  - building a custom image containing much of what we need
    for testing; and
  - copying other needed images to quay.io

(Reason: effective 2020-11-01 docker.io will limit the
number of image pulls).

The principal change is to create a new quay.io/libpod/testimage,
using the new test/system/build-testimage script, instead of
relying on quay.io/libpod/alpine_labels. We also switch to
using a hardcoded :YYYYMMDD tag, instead of :latest, in an
attempt to futureproof our CI. This image includes 'httpd'
from busybox-extras, which we use in our networking test
(previously we had to pull and run busybox from docker.io).

The testimage can and should be extended as needed for future
tests, e.g. adding test file content or other useful tools.

For the '--pull' tests which require actually pulling from
the registry, I've created an image with the same name but
tagged :00000000 so it will never be pulled by default.
Since this image is only used minimally, it's just busybox.

Unfortunately there remain two cases we cannot solve in
this tiny alpine-based image:

  1) docker registry
  2) systemd

For those, I've (manually) run:

    podman pull [ docker.io/library/registry:2.7 | registry.fedoraproject.org/fedora:31 ]
    podman tag !$ quay.io/...
    podman push !$

...and amended the calling tests accordingly.

I've tried to make the the smallest reasonable diff, not the
smallest possible one. I hope it's a reasonable tradeoff.

Ed Santiago d254fa4c35 system tests: enable more remote tests; cleanup
info, images, run, networking tests: remove some skip_if_remote()s
that were added in the varlink days. All of these tests now seem
to work with APIv2.

help test: check that first output line from 'podman --help'
is the program description (regression check for #7273).

load test: clean up stray images, rewrite test to make it conform
to existing convention. In the process, discover and file #7337

exec test (and networking): file #7360, and add FIXME comment
to skip()s suggesting evaluating those tests once that is fixed.

pod test: now that #6328 is fixed, use 'podman pod inspect --format'
instead of relying on jq

Various other tests: add an explanation of why test is disabled
so we can more easily distinguish "this will never be meaningful
under remote" vs "hey, doesn't work for now, but maybe someday".

  on a large byte transfer

- pod: add 'pod exists' tests, both positive and negative;
  consolidate tests; add '--label', and check in 'pod inspect'
  add 'pod ps' tests

  with --userns=keep-id would not forward a port

Ed Santiago fab5b35b2a Friendly amendment: tests, and a help message
1) Help message for podman port was missing [PORT]

2) Add test for 'podman port'. And, actually, an entire
   networking test that I'd written some weeks ago but
   apparently didn't 'git add'.
