Added configuration paramters to dhcp4 and its spec file to support DHCP-DDNS.
Created new classes D2ClientMgr, D2ClientConfig, and D2CientConfigParser in the
libdhcpsrv.   The new parameters are parsed, validated, and stored  but do
not yet affect behavior.  That will be implemented as a seperate ticket.
