[PATCH v2 1/5] doc: add documentation for OPT_STRING_LIST

[Jacob Keller <jacob.e.keller@intel.com>]

From: Jacob Keller <jacob.keller@gmail.com>

Commit c8ba16391655 ("parse-options: add OPT_STRING_LIST helper",
2011-06-09) added the OPT_STRING_LIST as a way to accumulate a repeated
list of strings. However, this was not documented in the
api-parse-options documentation. Add documentation now so that future
developers may learn of its existence.
