When graphroot is set by the user, we should set libpod's static
directory to a subdirectory of that by default, to duplicate
previous behavior.

Previous commits ensured that we would use database-configured
paths if not explicitly overridden.
However, our runtime generation did unconditionally override
storage config, which made this useless.
Move rootless storage configuration setup to libpod, and change
storage setup so we only override if a setting is explicitly
set, so we can still override what we want.

To configure runtime fields from the database, we need to know
whether they were explicitly overwritten by the user (we don't
want to overwrite anything that was explicitly set). Store a
struct containing whether the variables we'll grab from the DB
were explicitly set by the user so we know what we can and can't
overwrite.
This determines whether libpod runtime and static dirs were set
via config file in a horribly hackish way (double TOML decode),
but I can't think of a better way, and it shouldn't be that
expensive as the libpod config is tiny.

we need to allow users to expose ports to the host for the purposes
of networking, like a webserver. the port exposure must be done at
the time the pod is created.
strictly speaking, the port exposure occurs on the infra container.

We are still requiring oci-systemd-hook to be installed in order to run
systemd within a container. This patch properly mounts
/sys/fs/cgroup/systemd/libpod_parent/libpod-UUID on /sys/fs/cgroup/systemd inside of container.
Since we need the UUID of the container, we needed to move Systemd to be a config option of the
container.

This is an incomplete fix, as it would be best for the libpod library to be in charge of coordinating the container's dependencies on the infra container. A TODO was left as such. UTS is a special case, because the docker library that namespace handling is based off of doesn't recognize a UTS based on another container as valid, despite the library being able to handle it correctly. Thus, it is left in the old way.

And add an argument to WithHooksDir to set it.
If the hook dir doesn't exist, the new hooks package considers that a
fatal error. When a podman caller sets
--hooks-dir-path=/some/typoed/directory, a fatal error is more helpful
than silently not loading any hooks. However, callers who call podman
without setting --hooks-dir-path may not need hooks at all. We don't
want to pester those callers with not-exist errors. With this commit,
we:
* Assume the caller knows what they're doing if they set
--hooks-dir-path and set HooksDirNotExistFatal.
* If the caller does not explicitly set --hooks-dir-path, assume they
won't mind if the hook directory is missing and set
HooksDirNotExistFatal false.
We also considered checking for the directory's existence in the code
calling WithHooksDir or from within WithHooksDir, but checks there
would race with the underlying ioutil.ReadDir in the hooks package.
By pushing the warn/error decision down into libpod's implementation,
we avoid a racy "do we expect this to work once libpod gets to it?"
pre-check.
I've also added a check to error if WithHooksDir is called with an
empty-string argument, because we haven't defined the semantics of
that (is it clearing a previous value? Is it effectively the same as
the current directory?). I agree with Matthew that a separate
WithNoHooks, or a *string argument to WithHooks, or some such would be
a better API for clearing previous values [1]. But for now, I'm just
erroring out to fail early for callers who might otherwise be
surprised that libpod ignores empty-string HooksDir.
