Previously libpod CI was fairly straight-forward, run unit and
integration tests in a standard set of 3 VMs. Off on the side was a
single special case of running tests as an ordinary user. There is a
desire to stop using the PAPR system to support testing inside of a
container.
Since having two special cases potentially invites more
down the road, make provisions to handle them more gracefully. This
commit introduces an environment variable: ``$SPECIALMODE``. It's
value has the following meanings within the CI scripts:
Mode 'none': Nothing special, business as usual (default)
Mode 'rootless': Rootless testing
Mode 'in_podman': Build container, run integration tests in it.
This will make adding additional special-cases later easier, as well as
extending the special cases in a Matrix across multiple OS's.

Until recently it was very difficult to execute any scripts if part of a
task failed. A new feature in Cirrus-CI makes this easy. Use it to
post a notice on IRC when any task fails.
Also: Add quotes around yaml-string values for consistency and
syntax-highlighting correctness.

Certain integration tests require execution as a regular user.
This is acomplished by `PodmanTest.PodmanAsUserBase()` wrapping a
specialized execution environment, in `test/utils/utils.go`. However,
doing this requires passing through python, which vastly increases the
complexity of debugging low-level problems.
This commit introduces a new parallel task, run as a regular user on the
VM as set by three environment variables. All commands executed in the
``rootless_test.sh`` script, will occur as a real user with a name and
home directory, just as `$DIETY` intended. All env. vars established
during `environment_setup.sh` (for root) are available. The PR source
in `$GOSRC` and `$GOPATH` are owned by this user, and ready for use.

There is no native package for this, so the packaged version must also
be installed, otherwise all the support/dependencies would be removed
also (like go-md2man). Fix this by installing from the google released
tarball, into /usr/local/go and set $GOROOT to point there.
Also, include a small fix for hack/get_ci_vm.sh not installing
testing dependencies because of an old assumption.

This was specifically disabled early on in transitioning to cirrus due to
an excessive number of test failures and lack of knowledge. This commit
reverses the stance and unifies build and test commands across all
current platforms.

Previously we only reported the date/time at the beginning of a run
since it's not available in the Cirrus-CI system. This commit
generalizes the solution, recording start/end times for all major
events.
Also the timestamps are recorded into a local file on the VMs. This
is intended for future use, for example tracking execution-time
trends.

For all in testing involved distribution a new enough CRIU exists as a
package.
Fedora provides CRIU packages directly. For CentOS/RHEL there is a COPR
with the latest CRIU version and for Ubuntu there is a PPA for the
latest CRIU version. Let's use these packages and fall back to building
from git if necessary.

Frequently debugging of CI-related problems requires going hands-on
within the environment. However, reproducing the environment by hand is
very tedious and error prone. This script permits authorized users to
produce VM's based on any available cache-image, and automatically remove
them upon logout.
Also: Bump up VM disk sizes to 200GB due to performance reasons

A number of images required for future testing are not present in GCE.
Importing them is a long proscribed process prone to errors and
complications.
Improve this situation by documenting, and encoding the majority of the
steps required. Due to the required complexity, these are clearly
identified as 'semi-automated'. This means a discerning eye is
sometimes needed to address unforeseen problems (networking issues,
format or packaging changes, etc).
Nevertheless, having these steps in writing, will reduce current and
future maintenance burden while supporting future testing needs of
RHEL, Fedora and Fedora Atomic Host.
Also:
* Add necessary configuration, scripts, and Makefile updates needed to
prepare RHEL, Fedora, & FAH cloud images for use in GCE. This
is a complex, multi-step process where the cloud image is booted
un a local user-mod qemu-kvm instance, where it can be modified.
From there, it's converted into a specific format, and imported into
GCE. Lastly, the imported raw disk data is made available as a GCE
VM image.
Note: As of this commit, the RHEL base-image builds (CentOS has native
image), however neither RHEL or CentOS cache-images build correctly.
* Left testing on FAH disabled, the GCE/Cirrus integration needs needs more
work. Specifically, the python3-based google startup script service
throws a permission-denied (as root) when trying to create a temp.
directory. Did not investigate further, though manually running the
startup script does allow the libpod tests to start running.
* Enabled Fedora 29 image to execute tests and general use.
* Utilize the standardized F28-based container image for gating
of more the intensive unit and integration testing. Update
documentation to reflect this as the standard platform for
these checks. Rename tasks with shorter names and to better
reflect their purpose.
* Cirrus: Trim unnecessary env vars before testing since the vast
majority are only required for orchestration purposes. Since most
are defined within `.cirrus.yml`, it's a good place to store the
list of undesirables. Since each of the cirrus-scripts runs in
it's own shell, unsetting these near the end will have no
consequence. Also trim down the number of calls to show_env_vars()

The packer tool takes JSON as input for the details of producing VM
images to be used for PR CI-testing. JSON is not a very human-friendly
format, without support for comments and frequently containing lots of
duplicate data.
Fix this by using a Makefile + simple python one-liner to convert
from a human-friendly YAML format into packer-native JSON. This allows
use of anchors/aliases to reduce duplication, and allows inline comments
for easier maintainability. This also allows separating the 'test'
action from the 'build' action, for earlier and better syntax problem
detection.
Lastly, there are some minor ``lib.sh`` and ``integration_test.sh``
updates to support future work, and slightly improve the build and
test environments.

Previously, several magic strings were in place to affect cirrus-ci
operations. Two were buried within scripts. One to optionally
execute system-tests within a PR. Another to avoid re-building
cache-images upon every merge.
Move these magic strings out into the open, buy locating their
logic up-front in the ``.cirrus.yml`` file. This improves
readability and reduces surprise/astonishment at runtime.

An invalid GCE value is being passed to packer, preventing it from
building VM images. Fix this, and centralize the definition of the
image name suffix by setting it at ``setup_environment.sh`` call-time,
rather encoding inside packer's `libpod_images.json`. This makes
the value available for use by other scripts.
Also, switch the unique component of the name, to be based on the
commit-sha being tested. This will improve traceability, since the git
history is more permanent than the `CIRRUS_BUILD_ID` env. var. The
later is subject to log-rotation, destroying evidence of the images
source state.

Testing podman requires exercising on a full-blown VM. The current
containerized-approach is complicated, and mostly a band-aid over
shortcomings in the other CI systems. Namely, we want:
* To pre-build environments with dependencies to reduce the
setup time needed for testing.
* The ability to verify the pre-built environments are working
before utilizing them for further testing.
* A simple, single set of flexible automation instructions to
reduce maintenance burden.
* Ease of environment reproduction across clouds or locally, for
debugging failures.
This change leverages Cirrus-CI + Packer + collection of shell scripts
to realize all of the above.
