fix(confd): simplify check_cmd and fix grep usage

Changes the confd check_cmds to properly use the pre-templated
{{ .src }} file and fixes a misuse of grep.
fix(registry): use confd templated config

A regression from #1190 was introduced where the config file used
was the sample that came from dotcloud/docker-registry instead of
using the confd templated config we use today. Updating the file
to upstream's changes with the common layer as well as changing
the reference to the file in the Dockerfile fixes this regression.

docs(reference): update client reference link

The client documentation should handle an internal link to client,
while the client reference should also get its own. There are no
known links to the client reference docs, so no other changes are
necessary at this time.
docs(reference): update reference guide
docs(reference): use deis <command> as title

This makes it such that when you reference the command in the
documentation as ":ref:`deis_releases`", it shows up as "deis releases".
