Merge to develop for final release

[thetutlage]

• Remove container binding Adonis/Addons/Limiter in favor of container services and limiter.manager binding.
• The import path for the limiter service has been change.

  - import { Limiter } from '@adonisjs/limiter/build/services'
  + import limiter from '@adonisjs/limiter/services/main'

• Remove HttpLimiterConfigBuilder in favor of HttpLimiter. The API is still the same.
• Remove Throttle middleware, since limiterManager.define method now returns a middleware function that can be applied to routes directly.
• Remove property LimiterResponse.retryAfter in favor of LimiterResponse.availableIn.

Breaking change in HTTP limiters

The HTTP limiters defined using the Limiter.define method have been refactored and now the limiter.define method returns a middleware function that can be applied to a route. Following is a brief diff for the same.

Earlier

import { Limiter } from '@adonisjs/limiter/build/services'

export const { limiters } = Limiter
  .define('global', (ctx) => {
    return Limiter.allowRequests(1000).every('1 min')
  })

// INSIDE ROUTES FILE
Route.get('/api/reports/:id', () => {
}).middleware('throttle:global')

Now

import limiter from '@adonisjs/limiter/services/main'

export const throttle = limiter.define('global', (ctx) => {
  return limiter.allowRequests(1000).every('1 min')
})

// INSIDE ROUTES FILE
import { throttle } from '#start/limiter'

router.get('/api/reports/:id', () => {
}).use(throttle)

Features

• Add clear method to stores and limiter manager to clear all the rate limiting data from the store. This could be helpful during testing. See docs for usage information.
• Add limiter.attempt method run a callback if rate limiter requests have not been exhausted.
• Add limiter.penalize method to exhaust requests when the provided callback throws an exception.
• Add availableIn method to get the number of seconds to wait before the key becomes available.

Improvements

• The config file has been improved a lot with usage of functions and there is no need for contracts/limiter.ts file.
