This adds three tests for the --ignore-rootfs option to verify that it
works in all combination.
1. Not used at all
2. Only used during restore
3. Only used during checkpoint

This tries to reduce CI errors which might happen due to parallel CI
runs which all are using the same IP addresses. Using random addresses
should reduce the possibility of parallel tests using the same IP address.

A container restored from a checkpoint archive used to have the root
file-system mounted with a wrong (new) SELinux label. This made it, for
example, impossible to use 'podman exec' on a restored container.
This test tests exactly this. 'podman exec' after 'podman container restore'.
Unfortunately this test does not fail, even without the patch that fixes
it as the test seems to run in an environment where the SELinux label of
the container root file-system is not relevant. Somehow.

The option to restore a container from an external checkpoint archive
(podman container restore -i /tmp/checkpoint.tar.gz) restores a
container with the same name and same ID as id had before checkpointing.
This commit adds the option '--name,-n' to 'podman container restore'.
With this option the restored container gets the name specified after
'--name,-n' and a new ID. This way it is possible to restore one
container multiple times.
If a container is restored with a new name Podman will not try to
request the same IP address for the container as it had during
checkpointing. This implicitly assumes that if a container is restored
from a checkpoint archive with a different name, that it will be
restored multiple times and restoring a container multiple times with
the same IP address will fail as each IP address can only be used once.

The difference between container checkpoint/restore and container
migration is that for migration the container which was checkpointed
must not exist during restore. To simulate migration the container
is remove ('podman rm -fa') before being restored. The migration test
does following steps:
* podman run
* podman container checkpoint -l -e /tmp/checkpoint.tar.gz
* podman rm -fa
* podman container restore -i /tmp/checkpoint.tar.gz

when doing localized tests (not varlink), we can use secondary image
stores as read-only image caches. this cuts down on test time
significantly because each test does not need to restore the images from
a tarball anymore.

Only Fedora 29 and newer has an updated container-selinux and
selinux-policy new enough to support CRIU in restoring threaded
processes in a container with SELinux enabled.
Also skip checkpoint/restore tests if rootless. CRIU requires root.

To be able to use OCI runtimes which do not implement checkpoint/restore
this adds a check to the checkpoint code path and the checkpoint/restore
tests to see if it knows about the checkpoint subcommand. If the used
OCI runtime does not implement checkpoint/restore the tests are skipped
and the actual 'podman container checkpoint' returns an error.

There is currently still one SELinux related checkpoint/restore problem:
https://github.com/containers/libpod/issues/2334
To avoid unnecessary CI failures the checkpoint/restore tests are
temporarily disabled on Fedora.
It is not necessary to disable the tests on Ubuntu as it is running
without SELinux and it is also not necessary to disable the RHEL 7 tests
as RHEL's CRIU is too old to run the checkpoint/restore tests at all.

Add the ability to run the integration (ginkgo) suite using
the remote client.
Only the images_test.go file is run right now; all the rest are
isolated with a // +build !remotelinux. As more content is
developed for the remote client, we can unblock the files and
just block single tests as needed.

Restoring a container from a checkpoint should give the container the
same IP as before checkpointing. This adds a test to make sure the IP
stays the same.
