feature: Custom path and message after create update and delete

[Paul-Bob]

Description

Besides after_create_path and after_update_path it's possible now to override the method after_destroy_path. This three methods gives the path to redirect after the create, update and destroy succeed.

It's also possible to customize the messages for each action (create, update and destroy) success or fail by overriding:

• Create Success -> create_success_message Error -> create_fail_message
• Update Success -> update_success_message Error -> update_fail_message
• Destroy Success -> destroy_success_message Error -> destroy_fail_message

Now it's possible to override completely the response of each CrUD action both on success and failure:

• Create Success -> create_success_action Error -> create_fail_action
• Update Success -> update_success_action Error -> update_fail_action
• Destroy Success -> destroy_success_action Error -> destroy_fail_action
