Allow multiple levels of nested sub-options in custom option space

Problem

A single level of sub options can be specified in custom option definition “spaces”, however multiple levels of nesting are not supported. For example, option 125.<4491>.123.1 + 2, or option 125.1.1, or CableLabs V6 options 17.<4491>.2170 + 2171. Sub option 2171 (CL_OPTION_CCCV6) is particularly difficult because it has its own 9 sub options that are normally under V4 Option 122.

Desired Solution

The custom option spaces allow the definition of multiple levels of nesting.
