Parser for option data values within a subnet.
This parser iterates over all entries that define options data for a particular subnet and creates a collection of options. If parsing is successful, all these options are added to the Subnet object.

Parses a list of options, instantiates them and stores in cfg.
This method expects to get a list of options in option_data_list, iterates over them, creates option objects, wraps them with option descriptor and stores in specified cfg.
| cfg | created options will be stored here |

| encapsulate | a boolean value indicating whether or not the parser should encapsulate options with suboptions. The default value is true (encapsulate). |
