Previously, metrics were behind a feature flag (which was enabled by
default), now it's always available, but still disabled by default.

The new metric is there to help gauge iocaine's uptime, without relying
on an external collector like `systemd_exporter`.

Rather than cloning `Iocaine` (along with the markov chain & everything)
all over the place, declare it shared state behind an `Arc<Mutex>`. This
should reduce the amount of cloning done noticably.

These are quite... simple, and cover little, but it's more than nothing!
While there, enable tests in the Nix package, so they're run in CI too.

This rebuilds the templating so that the *content* is no longer
pre-generated, only the parameters. It is up to the template (and some
newly implemented helper functions) to construct the output from those.

When configuring iocaine via environment variables, sections and
settings were separated by two underlines, but the `IOCAINE_` prefix
only had one. This felt weird, so now iocaine supports an `IOCAINE__`
prefix too, and keeps recognizing the old one too.
Documentation and examples updated to use the new naming. No mention of
the backwards compatibility - I'll just silently support that.

When calling `axum::serve`, use `.with_graceful_shutdown()` to register
a `ctrl+c` handler, so that Iocaine can be gracefully shut down. This
also allows gracefully shutting it down when running inside a container.
Fixes#1, thanks @alciregi!

The initial seed is used by the RNG, and the intended use is to allow
modifying the generated output without otherwise modifying the
configuration, while still being a static, controllable seed that can be
shared between instances if need be.
Thanks to @buherator@infosec.place for the idea!

This is expected to run through a systemd system service, with the
config file explicitly specified. Using XDG for the default config makes
little sense in that case, and ends up causing issues with a strict
systemd service file.
