BRSKI-CoAP lets us do the *ENROLLMENT* over CoAP, not the discovery.

These are the interactions, and I will try to give some names to the various
interactions in a future document, but suggestions most welcome.

1) pledge <-> Join Assistant (JA)
   Discovery of JA:   mDNS and/or M_FLOOD

2) Join Assistant *discovery* of Registrar
   in 6tisch, omitted, will be provisioned
   in ANIMA, uses GRASP M_DISCOVERY

3) Join Assistant tentative admission control (used in 6tisch, to provide
   {optional?} "move along" feedback.).
   6tisch, currently M_REQ_NEG/M_END over *TCP*, need to be fixed.

4) pledge <-> Registrar.
   in ANIMA, this is pledge---TCP/HTTPS---> Registrar (RFC7030)
   in 6tisch-zero-touch, this is Registrar ---CoAP/DTLS--> pledge [maybe EDHOC]
                   (CoMI: draft-ietf-netconf-keystore-00 )
   in 6tisch-minimal-security, this is pledge-->CoAP/EDHOC--> Registrar
