Cirrus: Document and codify base-image production

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()

+
+### Base-images
+
+Base-images are VM disk-images specially prepared for executing as GCE VMs.
+In particular, they run services on startup similar in purpose/function
+as the standard 'cloud-init' services.
+
+*  The google services are required for full support of ssh-key management
+   and GCE OAuth capabilities.  Google provides native images in GCE
+   with services pre-installed, for many platforms. For example,
+   RHEL, CentOS, and Ubuntu.
+
+*  Google does ***not*** provide any images for Fedora or Fedora Atomic
+   Host (as of 11/2018), nor do they provide a base-image prepared to
+   run packer for creating other images in the ``build_vm_images`` Task
+   (above).
+
+*  Base images do not need to be produced often, but doing so completely
+   manually would be time-consuming and error-prone.  Therefor a special
+   semi-automatic *Makefile* target is provided to assist with producing
+   all the base-images: ``libpod_base_images``
+
+To produce new base-images, including an `image-builder-image` (used by
+the ``cache_images`` Task) some input parameters are required:
+
+    *  ``GCP_PROJECT_ID``: The complete GCP project ID string e.g. foobar-12345
+       identifying where the images will be stored.
+
+    *  ``GOOGLE_APPLICATION_CREDENTIALS``: A *JSON* file containing
+       credentials for a GCE service account.  This can be [a service
+       account](https://cloud.google.com/docs/authentication/production#obtaining_and_providing_service_account_credentials_manually)
+       or [end-user
+       credentials](https://cloud.google.com/docs/authentication/end-user#creating_your_client_credentials]
+
+    *  ``RHEL_IMAGE_FILE`` and ``RHEL_CSUM_FILE`` complete paths
+       to a `rhel-server-ec2-*.raw.xz` and it's cooresponding
+       checksum file.  These must be supplied manually because
+       they're not available directly via URL like other images.
+
+    * ``RHSM_COMMAND`` contains the complete string needed to register
+      the VM for installing package dependencies.  The VM will be de-registered
+      upon completion.
+
+    *  Optionally, CSV's may be specified to ``PACKER_BUILDS``
+       to limit the base-images produced.  For example,
+       ``PACKER_BUILDS=fedora,image-builder-image``.
+
+The following process should be performed on a bare-metal CentOS 7 machine
+with network access to GCE.  Software dependencies can be obtained from
+the ``packer/image-builder-image_base_setup.sh`` script.
+
+Alternatively, an existing image-builder-image may be used from within GCE.
+However it must be created with elevated cloud privileges.  For example,
+
+```
+$ alias pgcloud='sudo podman run -it --rm -e AS_ID=$UID
+    -e AS_USER=$USER -v /home/$USER:/home/$USER:z cevich/gcloud_centos:latest'
+
+$ URL=https://www.googleapis.com/auth
+$ SCOPES=$URL/userinfo.email,$URL/compute,$URL/devstorage.full_control
+
+$ pgcloud compute instances create $USER-making-images \
+    --image-family image-builder-image \
+    --boot-disk-size "200GB" \
+    --min-cpu-platform "Intel Haswell" \
+    --machine-type n1-standard-2 \
+    --scopes $SCOPES
+
+$ pgcloud compute ssh centos@$USER-making-images
+...
+```
+
+When ready, change to the ``packer`` sub-directory, and run:
+
+```
+$ make libpod_base_images GCP_PROJECT_ID=<VALUE> \
+    GOOGLE_APPLICATION_CREDENTIALS=<VALUE> \
+    RHEL_IMAGE_FILE=<VALUE> \
+    RHEL_CSUM_FILE=<VALUE> \
+    PACKER_BUILDS=<OPTIONAL>
+```
+
+Assuming this is successful (hence the semi-automatic part), packer will
+produce a ``packer-manifest.json`` output file.  This contains the base-image
+names suitable for updating in ``.cirrus.yml``, `env` keys ``*_BASE_IMAGE``.
+
+On failure, it should be possible to determine the problem from the packer
+output.  The only exception is for the Fedora and FAH builds, which utilize
+local qemu-kvm virtualisation.  To observe the serial-port output from those
+builds, set the ``TTYDEV`` parameter to your current device.  For example:
+
+```
+$ make libpod_base_images ... TTYDEV=$(tty)
+  ...
+```
