Keep the menu item for storage type consistent with other menu items in the storage submenu in the navigation module

Problem/Motivation

If you compare the menu entries for the storage module within the structure sub menu with others, you will notice that the storage module is the only one providing a sub sub menu containing an overview menu item and a menu item for the CTA to add a storage type, while others only provide a menu link to their list pages.

Steps to reproduce

• Install the navigation module
• Install the storage module
• Expand the top level menu item structure

Proposed resolution

I would stay consistent with the other menu links and simply provide a menu link called Storage types pointing to admin/structure/storage_types

Remaining tasks

User interface changes

API changes

Data model changes
