Comment:

 This is a straight forward change that allows D2 to be configured to
 disable updates in one
 a direction while allowing updates in the other direction to proceed.

 Added methods to D2CfgMgr to return whether or not forward or reverse
 updates are enabled.
 Altered D2UpdateMgr::makeTransaction to utilize these new methods.
 Added additional logs and unit tests.

 ChangeLog suggested:
 {{{
 7xx.    [func]      tmark
     b10-dhcp-ddns may now be configured to disable DNS updates in
     in a given direction by simply not defining any domains for that
     direction in its configuration.  This allows it be configured to
     support either forward DNS or reverse DNS only.  Prior to this if
     a request was received that could not be matched to servers in a
     given direction it was failed immediately.
     (Trac #3341, git TBD)
 }}}
