Missing `refillRate` on TokenBucket configuration causes error

[bendechrai]

Might be the lack of the required refillRate or the inclusion of an unknown fillRate, but the following config:

    tokenBucket({
      mode: "LIVE",
      capacity: 40,
      fillRate: 10,
      interval: 60,
    }),

Caused the following in DataDog:

Key: 'TokenBucketOptions.RefillRate' Error:Field validation for 'RefillRate' failed on the 'required' tag

Should probably return an error to the app, not the server.
