Return an array containing all of an object's keys. Note that the keys will be sorted as described in ReQL data types (for strings, lexicographically).

Example: Get all the keys from a table row.

// row: { id: 1, mail: "fred@example.com", name: "fred" }

r.table('users').get(1).keys().run(conn, callback);
// Result passed to callback
[ "id", "mail", "name" ]
