Removal of NICs/Disks page from Node Details page

When metal3-plugin is enabled it adds Disks and NICs tabs to Nodes details page.

We would like to remove these tabs becase:

• The same tabs are added to Bare Metal Hosts page - thus we would be removing the duplicity.

• Not every Node has to be backed by Bare Metal Host resource. If that is the case, then Disks/NICs tabs wont show anything.
