In swagger the attribute for required/optional is 'required', so we've decided that's a better way to specify our parameters. This changes the sphinx parser to use that when inserting (optional) into the table. We also make all 'path' parameters required, because we never specify them in a table where they are not. I think them all being required: false was an artifact of the data processing. Part of bp:api-ref-in-rst Change-Id: Ie2d012741d69430546fe1b10c9f16c853acb926a
