Inserts a row into the associated Mongo collection using the attribute values of this record.

This method performs the following steps in order:

1. call [[beforeValidate()]] when `$runValidation` is true. If validation
fails, it will skip the rest of the steps;
2. call [[afterValidate()]] when `$runValidation` is true.
3. call [[beforeSave()]]. If the method returns false, it will skip the
rest of the steps;
4. insert the record into collection. If this fails, it will skip the rest of the steps;
5. call [[afterSave()]];

In the above step 1, 2, 3 and 5, events [[EVENT_BEFORE_VALIDATE]],
[[EVENT_BEFORE_INSERT]], [[EVENT_AFTER_INSERT]] and [[EVENT_AFTER_VALIDATE]]
will be raised by the corresponding methods.

Only the [[dirtyAttributes|changed attribute values]] will be inserted into database.

If the primary key  is null during insertion, it will be populated with the actual
value after insertion.

For example, to insert a customer record:

```php
$customer = new Customer();
$customer->name = $name;
$customer->email = $email;
$customer->insert();
```

@param bool $runValidation whether to perform validation before saving the record.
If the validation fails, the record will not be inserted into the collection.
@param array $attributes list of attributes that need to be saved. Defaults to null,
meaning all attributes that are loaded will be saved.
@return bool whether the attributes are valid and the record is inserted successfully.
@throws \Exception in case insert failed.
