This rephrases and expands the definition of pods in an attempt to be:
a) much more explicit about what technically constitutes a pod;
b) agnostic towards particular container implementations.
A change along these lines will be critical as Kubernetes starts to
support alternative container runtimes (for example, #2725).
In trying to be as clear as possible, this turned into a larger rewrite
than I had originally anticipated, but I am fairly confident that it is
still effectively a no-op in terms of the current Kubernetes
implementation. But I stand correctable :-).
The change also introduces some other minor cleanup and drops the
link to the `lmctfy` paper, which seemed like a tenuous reference
(perhaps there is something more specific within the lmctfy project we
could link to instead?)
The pods.md document was referring to the networking.md document, and
was including the docs/ prefix, which led to a 404 due to the link being
https://$host/docs/docs/networking.md. Removing the docs/ prefix gets
the link working again.
This commit addresses issue #1571, which requests that all internal
Kubernetes links are swapped to relative ones to better facilitate
browsing of documentation on local forks, not to mention make the
documentation have less needless boilerplate.
