Benchmarks repository - requirements and ownership

[Jim MacArthur <jim macarthur codethink co uk>]

Hi all,

I've made an attempt to condense the requirements from the recent email 
thread ("Automated benchmarks of Buildstream", 
https://mail.gnome.org/archives/buildstream-list/2018-February/msg00012.html) 
and Antoine's thread from 2017 ("Benchmarking BuildStream commands from 
user point of view", 
https://mail.gnome.org/archives/buildstream-list/2017-November/msg00001.html). 
The candidate is up at 
https://gitlab.com/BuildStream/benchmarks/merge_requests/7. I haven't 
included every detail from those mailing list discussions. If you want 
to add something, please feel free to comment on the MR.

The benchmarks repository does not have any official maintainers at the 
moment. Since Sam Thursfield is no longer on the project full-time, I'm 
going to suggest I make myself the maintainer, unless anyone objects. It 
would be good to have a second person listed.
