     * Constructor.

     * List of available options:
     *  * database: The name of the database [required]
     *  * collection: The name of the collection [required]
     *  * id_field: The field name for storing the session id [default: _id]
     *  * data_field: The field name for storing the session data [default: data]
     *  * time_field: The field name for storing the timestamp [default: time]
     *  * expiry_field: The field name for storing the expiry-timestamp [default: expires_at]
     *  * ttl: The time to live in seconds.
     *
     * It is strongly recommended to put an index on the `expiry_field` for
     * garbage-collection. Alternatively it's possible to automatically expire
     * the sessions in the database as described below:
     *
     * A TTL collections can be used on MongoDB 2.2+ to cleanup expired sessions
     * automatically. Such an index can for example look like this:
     *
     *     db.<session-collection>.createIndex(
     *         { "<expiry-field>": 1 },
     *         { "expireAfterSeconds": 0 }
     *     )
     *
     * More details on: https://docs.mongodb.org/manual/tutorial/expire-data/
     *
     * If you use such an index, you can drop `gc_probability` to 0 since
     * no garbage-collection is required.
     *
     * @throws \InvalidArgumentException When "database" or "collection" not provided
