/**
* Overrides Mollom::__construct().
*
* This class accounts for multiple scenarios:
* - Straight low-level requests against the testing API from a custom script,
* caring for API keys on its own.
* - Whenever the testing mode is enabled (either through the module's
* settings page or by changing the testing_mode system variable),
* the client requires valid testing API keys to perform any calls. Testing
* API keys are different to production API keys, need to be created first,
* and may vanish at any time (whenever the testing API server is
* redeployed). Since they are different, the class stores them in different
* system variables. Since they can vanish at any time, the class verifies
* the keys upon every instantiation, and automatically creates new testing
* API keys if necessary.
* - Some automated unit tests attempt to verify that authentication errors
* are handled correctly by the class' error handling. The automatic
* creation and recovery of testing API keys would break those assertions,
* so said tests can disable the behavior by preemptively setting
* $createKeys or the 'mollom.testing_create_keys' state variable to FALSE,
* and manually create testing API keys (once).
*
* Constructor.
* @param ConfigFactory $config_factory
* @param ClientInterface $http_client
*
* @see Mollom::__construct().
