As issue #25112 points out, it was possible to start a machine on one of the darwin providers and then switch providers and start another one with a different name. This PR firstly prevents that use which is a forbidden use case.
Secondarily, performed some minor cleanup on the error messages being used so that the error would be specific to this condition.
This bug fix is for darwin only. In the case of Windows, we probably need to answer the question I raised in #24067 first, which is whether we want to stop allowing WSL to run multiple machines.

Instead of ErrVMAlreadyRunning use a more appropriate error.
Also improve the message a little bit.

Currently all podman machine rm errors in AfterEach were ignored.
This means some leaked and caused issues later on, see #22844.
To fix it first rework the logic to only remove machines when needed at
the place were they are created using DeferCleanup(), however
DeferCleanup() does not work well together with AfterEach() as it always
run AfterEach() before DeferCleanup(). As AfterEach() deletes the dir
the podman machine rm call can not be done afterwards.
As such migrate all cleanup to use DeferCleanup() and while I have to
touch this fix the code to remove the per file duplciation and define
the setup/cleanup once in the global scope.

We need to take another lock to prevent concurrent starts from different
machines.
I manually tested it by starting three VM in parallel with:
podman machine start & podman machine start test1 & podman machine start test2
I also added a CI test that seems to work as expected (failed with the
old binary, worked with the new)
Before this patch I was able to start more than VM, with this patch it
now only starts one of them and the other ones will fail to start with
a proper error.

The following PR is the leading PR for refactoring podman machine with
the following goals:
* less duplication/more re-use
* common configuration file between providers
* more consistentency in how machines are handled by providers
The goal of this PR is the rough refactor. There are still rough spots
for sure, specifically around the podman socket and pipe. This
implemention is only for Linux. All other providers are still present
but will not compile or work. This is why tests for them have been
temporarily suspended.
The ready socket code is another area that needs to be smoothed over.
Right now, the ready socket code is still in QEMU. Preferably it would
be moved to a generic spot where all three approaches to readiness
socket use can be defined.
It should also be noted:
* all machine related tests pass.
* make validate for Linux passes
* Apple QEMU was largely removed
* More code pruning is possible; will become clearer when other
providers are complete.
the dir pkg/machine/p5 is not permanent. i had to seperate this from
machine initially due to circular import problems. i think when all
providers are done (or nearly done), it can be placed and named
properly.

Previously, every machine created using appleHV interacted with VFKit using port 8081. This meant that if multiple machines existed on the machine, starting one would start all the machines. This patch assigns a separate random port for each machine, so machine commands interact with just the specified machine.

The following PR is the very first step in what will a series of steps
to apply a "common" machine configuration file to all providers.
Function names, method names, struct names, and field names are all up
for debate. The purpose of this PR is to offer a glimpse at the
direction we intend to take.
This PR also contains temporary structs (i.e. aThing) that are not
exported. These are merely placeholders.
The configuration work in this PR is also unused of yet. But the code
is compiled. Once merged, we can begin the next step of development.

I found the ginkgolinter[1] by accident, this looks for not optimal
matching and suggest how to do it better.
Overall these fixes seem to be all correct and they will give much
better error messages when something fails.
Check out the repo to see what the linter reports.

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.
