New user option 'kubed-list-mode-line-format'

* kubed.el (kubed-list-mode-line-format): New user option,
extracted from...
(kubed-define-resource): ...here.  Use it in 'mode-name' of
generated major modes.  This allows users to customize the indicator
we show in the mode line when update is in progress.
* kubed.texi (Browse Resources): Document new user option.
* NEWS.org: Announce it.
