The daemon has made a habit of mutating the DefaultRuntime and Runtimes
values in the Config struct to merge defaults. This would be fine if it
was a part of the regular configuration loading and merging process,
as is done with other config options. The trouble is it does so in
surprising places, such as in functions with 'verify' or 'validate' in
their name. It has been necessary in order to validate that the user has
not defined a custom runtime named "runc" which would shadow the
built-in runtime of the same name. Other daemon code depends on the
runtime named "runc" always being defined in the config, but merging it
with the user config at the same time as the other defaults are merged
would trip the validation. The root of the issue is that the daemon has
used the same config values for both validating the daemon runtime
configuration as supplied by the user and for keeping track of which
runtimes have been set up by the daemon. Now that a completely separate
value is used for the latter purpose, surprising contortions are no
longer required to make the validation work as intended.
Consolidate the validation of the runtimes config and merging of the
built-in runtimes into the daemon.setupRuntimes() function. Set the
result of merging the built-in runtimes config and default default
runtime on the returned runtimes struct, without back-propagating it
onto the config.Config argument.

Now that most uses of reexec have been replaced with non-reexec
solutions, most of the reexec.Init() calls peppered throughout the test
suites are unnecessary. Furthermore, most of the reexec.Init() calls in
test code neglects to check the return value to determine whether to
exit, which would result in the reexec'ed subprocesses proceeding to run
the tests, which would reexec another subprocess which would proceed to
run the tests, recursively. (That would explain why every reexec
callback used to unconditionally call os.Exit() instead of returning...)
Remove unneeded reexec.Init() calls from test and example code which no
longer needs it, and fix the reexec.Init() calls which are not inert to
exit after a reexec callback is invoked.

cmd.Wait is called twice from different goroutines which can cause the
test to hang completely. Fix by calling Wait only once and sending its
return value over a channel.
In TestLogsFollowGoroutinesWithStdout also added additional closes and
process kills to ensure that we don't leak anything in case test returns

- Inline `appendDocker()` into `Docker()` as it was the only place it was used,

Some of these tests are failing (but not enabled in CI), but the current output
doesn't provide any details on the failure, so this patch is just to improve the
test output to allow debugging the actual failure.
Before this, tests would fail like:

Contrary to popular belief, the OCI Runtime specification does not
specify the command-line API for runtimes. Looking at containerd's
architecture from the lens of the OCI Runtime spec, the _shim_ is the
OCI Runtime and runC is "just" an implementation detail of the
io.containerd.runc.v2 runtime. When one configures a non-default runtime
in Docker, what they're really doing is instructing Docker to create
containers using the io.containerd.runc.v2 runtime with a configuration
option telling the runtime that the runC binary is at some non-default
path. Consequently, only OCI runtimes which are compatible with the
io.containerd.runc.v2 shim, such as crun, can be used in this manner.
Other OCI runtimes, including kata-containers v2, come with their own
containerd shim and are not compatible with io.containerd.runc.v2.
As Docker has not historically provided a way to select a non-default
runtime which requires its own shim, runtimes such as kata-containers v2
could not be used with Docker.
Allow other containerd shims to be used with Docker; no daemon
configuration required. If the daemon is instructed to create a
container with a runtime name which does not match any of the configured
or stock runtimes, it passes the name along to containerd verbatim. A
user can start a container with the kata-containers runtime, for
example, simply by calling
docker run --runtime io.containerd.kata.v2
Runtime names which containerd would interpret as a path to an arbitrary
binary are disallowed. While handy for development and testing it is not
strictly necessary and would allow anyone with Engine API access to
trivially execute any binary on the host as root, so we have decided it
would be safest for our users if it was not allowed.
It is not yet possible to set an alternative containerd shim as the
default runtime; it can only be configured per-container.

This is a new attempt on making these tests less flaky. The previous attempt in
commit 585c147b7a assumed that the test was failing
if the test-daemon still had unrelated containers present from other tests, but
it appears that the actual reason for the tests to be flaky may be that the `--rm`
option was moved to the daemon side and an asynchronous operation. As a result,
the container may not yet be removed once the `docker run` completes, which happens
frequently on Windows (likely be- cause removing containers is somewhat slower
on Windows).
This patch adds a retry-loop (using `poll.WaitOn()`) to wait for the container
to be removed.

This attempts to fix CI flakiness on the TestRunContainerWithRmFlagCannotStartContainer
and TestRunContainerWithRmFlagExitCodeNotEqualToZero tests.
These tests;
- get a list of all container ID's
- run a container with `--rm`
- wait for it to exit
- checks that the list of all container IDs is empty
The last step assumes that no other tests are running on the same daemon; if
another test is running, there may be other containers present (unrelated to
the test).
This patch updates the tests to use a `docker inspect` to verify the container
no longer exists afterwards.
