The lazy-pages test case is not as straight forward as the other test
cases. This is related to the fact that restoring requires a different
name if restored on the same host. During 'runc checkpoint' the
container is not destroyed before all memory pages have been transferred
to the destination and thus the same container name cannot be used.
As real world usage will rather migrate a container from one system to
another than lazy migrate a container on the same host this is only
problematic for this test case.
Another reason is that it requires starting 'runc checkpoint' and 'criu
lazy-pages' in the background as those process need to be running to
start the final restore 'runc restore'.
CRIU upstream is currently discussing to automatically start 'criu
lazy-pages' which would simplify the lazy-pages test case a bit.
The handling and checking of the background processes make the test case
not the most elegant as at one point a 'sleep 2' is required to make
sure that 'runc checkpoint' had time to do its thing before looking at
log files.
Before running the actual test criu is called in feature checking mode
to make sure lazy migration is in the test case criu enabled. If not,
the test is skipped.

print out errors in checkpoint/restore log when it failed similar to how we did i
in `checkpoint --pre-dump` tests

We have two test cases with and without pre-dump. Terminals and
pre-dump features are orthogonal, so we can modify one of these test cases.

This adds targets for rootless integration tests, as well as all of the
required setup in order to get the tests to run. This includes quite a
few changes, because of a lot of assumptions about things running as
root within the bats scripts (which is not true when setting up rootless
containers).

CRIU gets pre-dump to complete iterative migration.
pre-dump saves process memory info only. And it need parent-path
to specify the former memory files.
This patch add pre-dump and parent-path arguments to runc checkpoint

This makes it much simpler to write tests, and you don't have to worry
about some of the oddness with bats.
