 The DHCP configuration parsers do not handle default values very well.
 This specifically refers to setting option values and option definitions.
 For example, the ''dhcp4'' is the default option space for each option.
 However, when leaving the default value the parser will simply receive
 partial configuration (that excludes space name). This in turn will cause
 an error message that the ''space'' parameter is missing. For this reason
 it is necessary to implement some conditions in option parsers that set
 default value for various parameters when they are not received from the
 Config Manager.
