Persist this model's changes to the database.

This will save all savable attributes like WP_Post objects or Models,
and persist any loaded relations.

The `saving` and `saved` events will be fired. If this model does not yet exist, the `creating` and `created`
events will fire as well. Otherwise, the `updating` and `updated` events will fire.

@since 2.0

@param array $options Configure how the saving should be performed.
Accepts 'exclude_relations' to allow for given relations to be excluded from persistence.

@return bool

@throws Exception
