Add link to the v3 client api doc

There was no link from the main page to the v3 client API doc so
there's no easy way to get to it or to know that it's there. This
adds the link.

Use admin_prefix consistently

The auth_admin_prefix config option is used manually in a number of
places where it could just be set for all requests.

Rely on OSLO.config

OSLO.config is now used by all the services. The hack in place to
correctly find the right config file is apparently (by way of the
comments) only required for the gate.

Therefore we should be able to remove this.

Remove http_handler config option in auth_token

This option was predominately used so that we could substitute a fake
handler in place so that we could mock our HTTP calls. This has been
replaced for some time now with httpretty so is no longer necessary.

Capitalize Client API title consistently

The "client v2 API" and "Client v2 API" titles were inconsistenly
capitalized. This makes the title capitalization consistent so the
index page looks better.

Privatize auth construction parameters

Privatize some of the automatic auth plugin construction work. At some
point we are going to need to have this pluggable and i'm not sure the
current methods will suffice. It's better to keep this private until we
are sure rather than be stuck with a public API.
