this pr allows the libpod integration suite to pass on the
ppc64le architecture. in some cases, I had to skip tests.
eventually, these tests need to be fixed so that they properly pass. of
note for this PR is:
* changed the ppc64le default container os to be overlay (over vfs) as vfs seems non-performant on ppc64le
* still run vfs for rootless operations
* some images names for ppc64le had to change because they don't exist.
* this should help getting our CI to run on the platform

Normally, we would not run system-tests as part of PR-level CI, they're
simply too heavy-weight and complex. However, in some instances it may
be desirable to provide a quick feedback loop, prior to release packaging
and official testing. Enable this by executing the system-tests when
a magic string is present in the PR description:
``***CIRRUS: SYSTEM TEST***``

Given frequent merges, it doesn't make sense to rebuild the VM testing
images every time. Instead, monitor the PR title and description for
a magic string, only triggering builds on a match:
***CIRRUS: REBUILD IMAGES***

Normally cirrus will abort jobs if another push is made to a branch.
However, with image builds, other VMs are created/managed by packer.
Therefor if cirrus aborts a task, it's possible some packer managed VMs
will be left behind. Disable this behavior for image-building only.

Occasionally, short-term temporary connectivity problems prevent ubuntu
from updating on GCE. As a workaround, attempt these commands twice.
Signed-off-by: Chris Evich <cevich@redhat.com>
Previously this was disabled as some package was breaking networking on
GCE after updating + rebooting. This is fixed now, so we should update
packages when building the fedora test VM image.

we are currently using something like /run/user/UID/run as runroot, as
it is already done by Buildah. This ends up with
/run/user/UID/run/runc for the runc directory. Change to drop the
additional /run so that runc will use /run/user/UID/runc.

If for any reason slirp4netns fails at startup, podman waits
indefinitely. Check every second if the process is still running so
that we avoid to hang.

conmon creates a symlink to avoid using a too long UNIX path.
Closes: https://bugzilla.redhat.com/show_bug.cgi?id=1641800
There is still one issue when the path length of the symlink has the
same length of the attach socket parent directory since conmon fails
to create the symlink, but that must be addressed in conmon first.

when the PS command was reworked for performance and formatting improvements,
i forgot to truncate the command field. Long container commands was throwing
the formatting off. we now truncated to 17 characters plus the elipses.

for backwards compatibility and auto-test, we needed a few changes
that slipped in when i reworked ps to be faster to be reverted. the
follow behaviours were reverted:
1. the is_infra column was redacted. that appears to be a mistake on my
part.
2. a newline after ps prints its format was added
3. a newline prior to printing the headers was removed.

Ed has asked that we revert to using two spaces for padding between PS fields. I assume
this is for docker autotests.

Only return `ErrCtrStateInvalid` errors when the mount counter is equal
to 1. Also fix the "can't unmount [...] last mount[..]" error which
hasn't been returned when the error passed to `errors.Errorf()` is nil.

for the purposes of performance and security, we use securejoin to contstruct
the root fs's path so that symlinks are what they appear to be and no pointing
to something naughty.
then instead of chrooting to parse /etc/passwd|/etc/group, we now use the runc user/group
methods which saves us quite a bit of performance.

Add a section about describing changes in commit messages. GitHub tends
to drive the large part of discussions and change descriptions to the
corresponding pull requests and issues, but such information is lost in
the git history. Not providing sufficient information in commit
messages is painful for reviewing and can cause issues while debugging.
It also complicates studying source code, where reading commit messages
and the code's git history is a common approach to better understand the
code.
Following the descriptions should be enforced by the maintainers of the
libpod project. Pull requests containing commits without proper
descriptions should not be merged.
This change bases on the documentation of the Linux kernel v4.17:

add a global flag for --max-workers so users can limit the number
of parallel operations for a given function. also, when not limited
by max-workers, we implement a heuristic function that returns the
number of preferred parallel workers based on the number of CPUs and
the given operation.

We implement the securejoin method to make sure the paths to /etc/passwd and
/etc/group are not symlinks to something naughty or outside the container
image. And then instead of actually chrooting, we use the runc functions to
get information about a user. The net result is increased security and
a a performance gain from 41ms to 100us.
