[Pki-devel] Interface doc changed (version 0.4)

[Ade Lee]

Hi all, 

Based on feedback from Jack on some KRA servlets, I have made a few
small modifications to the interface docs and flows.

In particular, added a couple flows for key generation and storage on
the DRM (server-side key gen), and key recovery when nAgents=1.
On the interface docs, made the types of POST-a to /pki/keyrequest more
explicit.
