Comment:

 This ticket introduces the initial implementation of !NameAddTranscation.
 This
 class derives from !NameChangeTransaction and provides the state model
 implementation to add DNS entries for a given FQDN.   With the completion
 of
 this ticket the state model logic is fully functional, and there are unit
 tests
 for each state's handler that verify all of the state model transitions.
 What remains to be done is to implement the logic necessary to construct
 the
 actual DNS update requests.  This effort has been split off into a new
 ticket,
 Trac #3241, to keep the amount of code under review more manageable.

 The following class diagram depicts the new class:

 model:

 I propose the following !ChangeLog entry:

 {{{
 6xx.    [func]  tmark

 Created the initial implementation of the class, NameAddTransaction,
 to b10-dhcp-ddns.  This class provides the state model logic described
 in the DHCP_DDNS design to add or replace forward and reverse DNS entries
 for a given FQDN.  It does not yet construct the actual DNS update
 requests.

 (Trac# 3087, git TBD)
 }}}
