Review by CA - Datagram v Connectionless

[gorryfair]

• "Connection establishment is only a local operation for a Datagram
  transport (e.g., UDP(-Lite))": I think the criterion is not Datagram
  transports but "transports without a handshake" or "connectionless
  protocols" as it is used later in the document.

[gorryfair]

I wrote, and I suggest we use "connectionless protocols" explicitly mentioning examples of UDP and UDP-Lite when used as a transport without a handshake.

To whoever plans to address this: I checked occurrences of the word "datagram" in the architecture and API drafts, and I found (only) one sentence that needs fixing on similar grounds, I think, in the API draft:

Guidance on setting this value for datagram transports is provided in [RFC8085].

in Section 8.1.4 "Timeout for keep alive packets". Surely the guidance regarding this matter in the UDP usage RFC is related to the fact that UDP(-Lite) is connectionless, not that it's datagram based.

Starting #1034 to fix this.
