Remove overrides reference from Manila-UI plug-in
Plug-ins should not be using the "customization_module" override mechanism to change default Horizon behavior. Any "override" code should live with the __init__.py file of the appropriate plug-in directory. Change-Id: Idc2c66e2994780298725535f00184d4e3f2f6bb9 Closes-Bug: #1485112
