These files were created with the executable bit set accidentally due
to the way my network file system setup was configured.

The Destination service used slightly different labels than the
telemetry pipeline expected, specifically, prefixed with `k8s_*`.
Make all Prometheus labels consistent by dropping `k8s_*`. Also rename
`pod_name` to `pod` for consistency with `deployement`, etc. Also update
and reorganize `proxy-metrics.md` to reflect new labelling.

Previously we were using the instance label to uniquely identify a pod.
This meant that getting stats by pod name would require extra queries to
Kubernetes to map pod name to instance.
This change adds a pod_name label to metrics at collection time. This
should not affect cardinality as pod_name is invariant with respect to
instance.

The Prometheus scrape config collects from Conduit proxies, and maps
Kubernetes labels to Prometheus labels, appending "k8s_".
This change keeps the resultant Prometheus labels consistent with their
source Kubernetes labels. For example: "deployment" and
"pod_template_hash".

The inject code detects the object it is being injected into, and writes
self-identifying information into the CONDUIT_PROMETHEUS_LABELS
environment variable, so that conduit-proxy may read this information
and report it to Prometheus at collection time.
This change puts the self-identifying information directly into
Kubernetes labels, which Prometheus already collects, removing the need
for conduit-proxy to be aware of this information. The resulting label
in Prometheus is recorded in the form `k8s_deployment`.

The Markdown files were all originally named "$x/_index.md"; I renamed
them as follows:
```
for x in `ls ~/conduit-site/conduit.io/content`; do
cp ~/conduit-site/conduit.io/content/$x/_index.md doc/$x.md
done
mv doc/doc.md doc/overview.md
```
When we publish the files on conduit.io we need to do the inverse
transformation to avoid breaking existing links.
The images were embedded using a syntax GitHub doesn't support. Also, the
images were not originally in a subdirectory of docs/.
Use normal Markdown syntax for image embedding, and reference the docs
using relative links to the images/ subdirectory. This way they will show
up in the GitHub UI. When we publish the docs on conduit.io we'll need to
figure out how to deal with this change.
I took the liberty of renaming data-plane.png to dashboard-data-plane.png to
clarify it a bit.
There is no other roadmap so there's no need to qualify this one as
"public." Before it was made public we marked it "public" to emphasize
that it would become public, but that isn't needed now.
