handle EndUserApiKeyRateLimitedException, 4.1.0

[mrmauer]

After PR

This introduces graceful handling of rate-limit-specific error thrown when validating an end user's api key. For example, you can now do this

try:
    auth.validate_api_key(end_user_api_key)
    return {"message": "Success"}
except EndUserApiKeyRateLimitedException as e:
    print(e)
    # Example
    # {
    #   'error_code': 'rate_limit_exceeded', 
    #   'user_facing_error': 'Your api keys have hit the rate limit. Wait 58.134504795074 seconds.', 
    #   'wait_seconds': 58.134504795074
    # }
    return {"message": f"Please wait {e.args[0]['wait_seconds']} seconds before trying again."}
except EndUserApiKeyException as e:
    print(e)
    return {"message": "Invalid API key"}
except Exception as e:
    print(e)
    return {"message": "Something went wrong..."}

Bumps version to 4.1.0

Tests

Confirmed expected behavior within an example application.
