sdn: preparations for DHCP plugin

Add the option to retrieve the running configuration instead of only
the pending configuration via the config methods. Refactor methods
using the running config to utilize the new parameter.

Add helper methods and return additional attributes from the getter
functions that are needed by the dhcp plugins.
