Selecting namespaces

To run kubens and select a namespace interactively:

$ kubens my-namespace

If there are multiple matches, it will show a menu to select from.

Listing namespaces

To list namespaces:

$ kubens --list

To list namespaces with a filter:

$ kubens --list ku

This will list namespaces that start with "ku".
