implement an easy way to switch namespaces

[srgvg]

Is your feature request related to a problem? Please describe.
I love using k9s. The only thing I find difficult is an easy way to switch namespaces.

Describe the solution you'd like
Provide an easy command and/or shortcut to quickly switch namespaces.
e.g. ctrl-n yields a namespace popup to select and filter on it.

Describe alternatives you've considered
Going :ns is too cumbersome.

@srgvg Thank you for your kind words! Imho this is where k9s shine vs similar browser based offerings.
Switching namespace in not an end to itself without specifying a resource i.e I am in ns-a and want to see deployment in ns-b. Having a ns selector popup, selecting/filtering, click ok and landing in the namespace default view seems like a much more involved user flow imho. While :dp ns-b gets you exactly where you want to be.

Thanks @derailed for considering my request. Allow me to further argue :-)

When I want to switch namespaces, I'm often already viewing the type of resources I'd like. Switching type of resources is a separate thing to me.
Now I find myself aliasing k9s=k9s --all-namespaces to more or less work around this, but obviously, on larger clusters filtering by a specific namespace might be preferred. Please allow me hence to disagree on stating that switching ns would not be an end in itself.

My muscles prefer a quick shortcut like e.g. ctrl-n in this case, which is much more quicker (at least to me) than the double targetting :dp ns-b.

I should add, that in my idea ctrl-n (or sth like that) would pop-up a quick list from where I can filter-select the needed namespace, with autocompletion.

I should also add that I wasn't aware I could do :ns mynam<TAB> which is almost what I had in mind....
