handle rate limit and implement retry logic

[smaeda-ks]

Adding rate limit handling and retry logic.

Usage

• rate-limit

  
  CONSUMER_KEY = 'your consumer key'
  CONSUMER_SECRET = 'your consumer secret'
  ACCESS_TOKEN = 'access token'
  ACCESS_TOKEN_SECRET = 'access token secret'
  ACCOUNT_ID = 'account id'

client = Client( CONSUMER_KEY, CONSUMER_SECRET, ACCESS_TOKEN, ACCESS_TOKEN_SECRET, options={ 'handle_rate_limit': True # default is False })

account = Account.load(client, ACCOUNT_ID) campaigns = Campaign.all(account)

- retry
```py
client = Client(
    CONSUMER_KEY,
    CONSUMER_SECRET,
    ACCESS_TOKEN,
    ACCESS_TOKEN_SECRET,
    options={
        'retry_max': 3,  # default is 0
        'retry_delay': 5000,  # milliseconds (default is 1500)
        'retry_on_status': [404, 500, 503]  # status codes you want to retry on
    })

account = Account.load(client, ACCOUNT_ID)
campaigns = Campaign.all(account)

• combine

  
  client = Client(
  CONSUMER_KEY,
  CONSUMER_SECRET,
  ACCESS_TOKEN,
  ACCESS_TOKEN_SECRET,
  options={
      'handle_rate_limit': True,  # default is False
      'retry_max': 3,  # default is 0
      'retry_delay': 5000,  # milliseconds (default is 1500)
      'retry_on_status': [404, 500, 503]  # status codes you want to retry on
  })

account = Account.load(client, ACCOUNT_ID) campaigns = Campaign.all(account)

### Test with actual requests
- code
```py
client = Client(
    CONSUMER_KEY,
    CONSUMER_SECRET,
    ACCESS_TOKEN,
    ACCESS_TOKEN_SECRET,
    options={
        'handle_rate_limit': True,
        'retry_max': 3,
        'retry_delay': 5000,
        'retry_on_status': [404, 500, 503]
    })

account = client.accounts(ACCOUNT_ID)

data = TargetingCriteria.locations(account, count=1)

for i in data:
    print(i['targeting_value'])
    print("rate_limit_remaining: {}".format(data.rate_limit_remaining))
