Subject: netns: T6295: disable incomplete support in VyOS 1.4 sagitta

The netns support currently available on the VyOS CLI is only a
proof-of-technology, we have no real support for any service behind it.

In order to not confuse anyone on the LTS branch we decided to remove the
netns option for interfaces until there is a proper usecase and implementation
available.
