+1 maintenance report

[Tiago Daitx]

My +1 maint last week started with me digging through some of the
other reports to find interesting things to work on but I quickly
noticed that having just 2 days for maint work (every other week)
meant I was spending quite some time trying to grasp the more complex
migrations and I was dearly missing a better way to contextualize and
visualize them. So I decided to try to plot the relationships from
update excuses to get an actual picture of it using graphviz.

I used ubuntu-archive-scripts/generate-team-p-m as a base and after
some modification and playing around with different ways to plot the
graphs I had something that seemed worthwhile to share, even if a bit
rough right now. The script is at:
https://github.com/tdaitx/canonical-tools/blob/master/generate-gv-from-update-excuses

I invite others to try it and I would highly appreciate PR's with
improved ways to represent the various states a package under
migration has.

Of the various graphviz tools, I find the 'fdp' tool to be the best
for plotting some complex graphs.

Example:
$ generate-gv-from-update-excuses --packages
dpkg,ruby-defaults,setuptools,libpcap,glib2.0,qpdf --components
main,universe --excuses-yaml update_excuses.yaml.xz upd_exc.gv
$ fdp -Tsvg upd_exc.gv > upd_exc.svg


Some ideas for improvements:
- allow excluding packages/sets
- represent 'reason' in the node somehow (label/style/color/shape)
- use urls/html for imap output (could link back to update excuses/autopkgtests)
- document or provide a legend of what each shapes/style means
