Andrew Rynhard 17093416e6 docs: add FAQs page
The FAQs should be pulled out from the documentation as they are
specific to a version of Talos and more of a marketing message. This
adds a dedicated page for the FAQs.

<h1>What is Talos?</h1>
<div>
<p>
Talos is a made up of a few pieces. The first piece is an
API-driven, purpose-built OS, based on Linux. Its entire purpose is
to host a Kubernetes cluster, so it is not a general purpose OS. The
OS consists of the Linux kernel, a simplified init system, and a
series of components that run in containers on the system, managing
things like connections between the nodes, routes and networking,
and serving APIs. It doesn't have SSH or a package manager. Instead,
all of the management of Talos happens over an API.
</p>
<p>
The second piece of Talos is <tt>osctl</tt>: the command-line
interface to manage your Talos-based Kubernetes cluster. It lets you
do all of the basic system administration on your cluster. You can
view process lists, download log files, and so forth. It's designed
specifically to help you debug problems on the cluster during
development and testing.

<h1>How is Talos different than CoreOS/RancherOS/Linuxkit?</h1>
<div>
<p>
Talos shares a lot of attributes with these systems, but there are
some important differences. Talos integrates tightly with
Kubernetes, and is not meant to be a general-purpose operating
system. The most important difference is that Talos is fully
controlled by an API via a gRPC interface, instead of an ordinary
shell. We don't ship SSH, and there is no console access. Removing
components such as these has allowed us to dramatically reduce the
footprint of Talos, and in turn, improve a number of other areas
like security, predictability, reliability, and consistency across
platforms. It's a big change from how operating systems have been
managed in the past, but we believe that API-driven OSes are the
future.

<h1>Why no shell or SSH?</h1>
<div>
<p>
Since Talos is fully API-driven, all maintenance and debugging
operations should be possible via the OS API. We would like for
Talos users to start thinking about what a "machine" is in the
context of a Kubernetes cluster. That is, that a Kubernetes
<i>cluster</i> can be thought of as one massive machine, and the
<i>nodes</i> are merely additional, undifferentiated resources. We
don't want humans to focus on the <i>nodes</i>, but rather on the
<i>machine</i> that is the Kubernetes cluster. Should an issue arise
at the node level, <tt>osctl</tt> should provide the necessary
tooling to assist in the identification, debugging, and remedation
of the issue. However, the API is based on the Principle of Least
Privilege, and exposes only a limited set of methods. We envision
Talos being a great place for the application of

in order to provide a self-healing platform.

<h1>Why the name "Talos"?</h1>
<div>
<p>
Talos was an automaton created by the Greek God of the forge to
protect the island of Crete. He would patrol the coast and enforce
laws throughout the land. We felt it was a fitting name for a
security focused operating system designed to run Kubernetes.
