Moving the parameters needs to be done before defaults are applied to the
config, so moveDdnsParams was changed to modify a mutable top level
element map instead of SrvConfig contents.

src/lib/dhcpsrv/parsers/simple_parser4.cc
src/lib/dhcpsrv/parsers/simple_parser6.cc
    Change ddns-send-updates default to true.

D2ClientMgr functions now get behavior parameters from a passed in
structure instead of D2ClientMgr::d2_client_config_.
