Allow configuring k9s to use all namespaces by default

[jflambert]

Currently using k9s v0.32.4

Is your feature request related to a problem? Please describe.
When using k9s I want to automatically use all namespaces (without having to add -A)

Describe the solution you'd like
A new entry in config.yaml would allow me to set -A as a default parameter.

Describe alternatives you've considered
alias k9s="k9s -A"

Additional context
I believe persisting "all namespace" used to work up until a few releases ago. It would also remember my last known location, etc.

It looks like I was affected by this bug!

#2578

When I use :q to quit instead of Ctrl+C, the default/default/config.yaml file is properly saved, and it remembers I want all namespaces, and which view I was in.

Still there might be a use case to force -A by default, so I'll let the project admin decide to keep or close my issue.

I was looking for that configuration. I still think it's relevant so folks don't have to quit with :q.

Also, the alias is not a proper solution, as it will cause errors for commands like k9s info for which you need to upgrade your alias for a function that will check if there is any other commands or flags and if not, ran k9s with the -A flag.

@jflambert I'm using 0.32.4 and indeed using :q instead of Ctrl+C does save the state. Thank you for that tip.

Edit: for now I also set noExitOnCtrlC to true in the config to avoid losing my state
