[pve-devel] [PATCH] tui: focus next button by default

[Dominik Csapak <d.csapak@proxmox.com>]

except the password dialog, since the user must provide input

to do that, we have to set the focus index on all relevant views

not sure if this is the correct approach, also the extra parameter feels
slightly wrong, but didn't found a nicer way to do this

any errors from focusing will be ignrored, but that shouldn't happen
anyway until we add/remove buttons and the index changes

alternatively we could create a second 'new_with_focus_next' (or
'without') that gets called respectively, but also seems a bit weird for
that
