In #20538, I was asked to consider refactoring the new OCI pull code
from within the generic machine directory. This is something I had
tried when originally coding it but it became apparent that a much
larger refactor to prevent circular deps was needed. Because I did not
want to pollute the initial PR with that refactor, I asked for the PR to
merge first. This is the refactor that needed to be done.

allow podman machine to extract its disk image from an oci registry or
oci-dir locally. for now, the image must be relatively inflexible. it
must have 1 layer. the layer must possess one image. so a dockerfile
like:
FROM scratch
COPY ./myimage.xz /myimage.xz
when using an oci dir, the directory structure must adhere to the
typical directory structure of a an oci image (with one layer).

in order to identify this new input, you must use a transport/schema to
differentiate from current podman machine init --image-path behavior. we
will support `oci-dir://` and `docker://` as transports.
when using the docker transport, you can only use an empty transport for
input. for example, `podman machine init --image-path docker://`. A
fully quailified image name will be supported in the next iteration.
the transport absent anything means, i want to pull the default fcos
image stored in a registry. podman will determine its current version
and then look for its correlating manifest. in this default use case,
it would look for:
quay.io/libpod/podman-machine-images:<version>
that manifest would then point to specific images that contain the
correct arch and provider disk image. i.e.
quay.io/libpod/podman-machine-images:4.6-qcow2
this PR does not enable something like
docker://quay.io/mycorp/myimage:latest yet.
names, addresses, andf schema/transports are all subject to change. the
plan is to keep this all undocumented until things firm up.

some problems were found in machine tests on hyperv.
in the case of rootful, it is currently not implemented. an issue #20092 has been
created for that problem.
there also seems to be a timezone issue between ignition and fcos right
now. inquiries are in for that but no issue generated for that. this
problem is not exclusive to hyperv by any means.
both of the above have been skipped or commented out.
otherwise, this fixes machine state reporting for consistency.

This PR is a mishmash of updates needed so that the hyperv provider can
begin to passd the machine e2e tests.
Summary as follows:
* Added custom error handling for machine errors so that all providers
can generate the same formatted error messages. The ones implemented
thus far are needed for the basic and init tests. More will come as
they are identified.
* Vendored new libhvee for better memory inspection. The memory type
changed from uint32 to uint64.
* Some machine e2e tests used linux-specific utilities to check various
error conditions and messages (like pgrep). Those were made into
functions and implemented on an operating system level.

this pr has the basic plumbing that allows the e2e machine tests to run
with the hyperv provider.
it requires a special fcos image right now because gvforwarder was not
in the upstream fcos images for hyperv.
changed the way "provider" is set; moved GetProvider functions to
pkg/machine/provider. provider is now set at the machine level.

As promised in #19596, this pr deduplicates and refactors image
acquisition. All virt providers that use FCOS as its default now use
the same code.

Ensures that for each hypervisor implementation, their `config.go` file
deals with implementing the `VirtProvider` interface while the
`machine.go` file is for implementing the `VM` interface.
Moves the `Virtualization` type into a common file and
created wrappers for the individual hypervisors. Allows for shared
functions that are exactly the same while providing the flexibility to
create hypervisor-specific implementations of the functions.

Directly writing to stdout/err is not safe when run in parallel.
Ginkgo v2 fixed this buffering the output and syncing the output so it
is not mangled between tests.
This is the same as for the podman integration tests.

in preparation for adding hyper as a machine option, several common
functions needed to be moved specifically from qemu to a common area in
pkg/machine. this usually involved functions and variables related to
using fcos as a machine image as well as its compression, artifact, and
image format.

before we can support hyperv as a virtualization option for podman
machine, several areas in machine will require cleanup. this is the
first pass of these changes to keep the review burden low. changes
include:
* convert artifact, format (image format) and compression to enums
with string methods
* rename Provider interface to VirtProvider
* change Provider implementation in QEMU to QEMUVirt
* change Provider implementation in WSL to WSLVirt
as mentioned earlier, there will be several more of these refactoring
PRs because assumptions were made about associations of platforms and
virt providers as well as compression and image formats.

Safe guards calls to os.RemoveAll in order to prevent calls from accidently
deleting the root file system in very strange edge cases. Did this by creating
GuardedRemoveAll and migrated machine os.RemoveAll calls to it.

Package `io/ioutil` was deprecated in golang 1.16, preventing podman from
building under Fedora 37. Fortunately, functionality identical
replacements are provided by the packages `io` and `os`. Replace all
usage of all `io/ioutil` symbols with appropriate substitutions
according to the golang docs.

Rename all files to _test.go and rename the package to e2e_test. This
makes the linter less strict about things like dot imports.
Add some unused nolint directives to silence some warnings, these can be
used to find untested options so someone could add tests for them.

This PR introduces a test suite for podman machine. It can currently be
run on developers' local machines and is not part of the official CI
testing; however, the expectation is that any work on machine should
come with an accompanying test.
At present, the test must be run on Linux. It is untested on Darwin.
There is no Makefile target for the test. It can be run like `ginkgo -v
pkg/machine/test/.`. It should be run as a unprivileged user.
