dodo-core-features: Add query parameter describe / parse feature to router

[elhigu]

Something like:

router.get('/')
  .query('paramName', { type: number, optional: true, doc: 'Number of things' })
  .query('paramName2', { type: number, optional: false, doc: 'Number of things' })
  .handler(function (req, res) {
    typeof req.query.paramName === 'number'; // this would be true
  });

type could be also function taking string as parameter and returning promise or value.
