b4 review tui: patchwork integration

Hi Konstantin,

It's great to have a built-in patchwork support!

Something that is blocking me to use 'b4 review tui' more is that not
all Patchwork status are supported, e.g. I cannot mark a patch as
"Queued", and delegate it to someone.

I see that patches are automatically marked as "under-review", but it
would be nice to assign myself as well, so others know who is reviewing
what. Eventually, it might be good to ask for a confirmation: I might
use the "review" mode simply to validate a patch reviewed by someone else.

Something that was already reported by someone else I think is that the
"patchwork" view only shows the "Action Required" ones, and it is not
possible to show more patches.

One last thing: it might be good to have other automations, e.g. when
the "Reviewed-by" tag is sent from the "review" mode, then the patch
could be marked as "Queued" on Patchwork.

(And eventually, have a way to run script as an action during the review
and from the "patchwork" view, e.g. to apply a patch using a script that
will do extra quick checks and select the right tree.)

Cheers,
Matt
