Add and enable pyflakes3 on console_conf, subiquity, subiquitycore and tests.
Replace NOQA markers with __all__ declarations for module imports.
Replace some obvious deadcode that voilates flake8, separate pass for removing
dead code rather than commenting will be handled later.
read title and footer from the view instance, make views respsonsible for rendering

adapts infrastructure, welcome, keyboard, network views
Before this change, subiquity has lots of ListBoxes that just contain a single
Pile containing all their contents. This is (a) a bit silly (b) make some parts
of the scrolling experience a bit poor, for example urwid tries to scroll all
of a ListBox element into view when it gets focus but this is defeated by
shoving all the elements into a Pile (this causes
https://bugs.launchpad.net/subiquity/+bug/1750058 and a few other strange
bits).
The fix for this is obvious (don't wrap ListBox elements in a Pile) but this
breaks some aspects of tab cycling (when you shift tab back into a listbox you
want the last element of the box to be both selected and scrolled into view,
that sort of thing). Fixing all these bits of broken behaviour required
rewriting the tab cycling implementation to the point of copy/paste/hack-ing
the Pile.keypress method. Rather than doing the same for Columns, I just
prevent the creation of Columns with more than 1 selectable, which as we want
subiquity to be navigable with up/down/return does not seem so bad.
As penitence for all this, I've added a bunch of commentary explaining what is
going on.
before this, if you press up on e.g. the network view, focus would go to the first nic
not the last as you might expect. this is pretty obscure but oh well. such is urwid.
Create palette for traffic light buttons: green (default), amber and
red. Color-code most buttons.
Make all progressbars orange for the completed part.
1) move the done / cancel buttons (and error display) out of scrolling region
2) focus done by default
3) update footer texts to make sense
4) use a bit more of the horizontal space to show interface information
