 * Tests how applyOps handles index specs with unknown fields.
 *
 * We subject index specs with version 2 or later to stricter validation than version 1 index specs.
 * When given an index spec with an unrecognized field, applyOps will reject v:2 indexes with an
 * InvalidIndexSpecificationOption error while v:1 indexes are accepted as-is.
