[Dime] DOIC: Sections 5.3.1 and 5.3.2

[Steve Donovan <[e-mail]>]

The wording in section 5.3.1 and 5.3.2 need to be aligned with the
reacting and reporting node concepts.  The wording "Request/Response
Message Initiator" is misleading in this context.  The "initiator" of
the message will be either a client or a server.  The logic being
discussed in 5.3.1 deals with the reacting node and the logic in 5.3.2
deals with the reporting node.  Given that an agent can be reacting
and/or reporting node but does not initiate the messages, I suggest
changing the titles to the sections to:

5.3.1 Reacting Node Endpoint Considerations

and

5.3.2 Reporting Node Endpoint Considerations

The text in the sections should also be updated to align with the
reacting node and reporting node concepts.
