This pull request adds a reduced 'staging' jobset to Cuirass, toprevent needless rebuilds outside of the freeze cycles.
It also adjusts the documentation to more closely match the currentstaging and core-updates practices.

I decided to scrap patch 1/2 in this series. Partly because it wouldnot work as-is, and partly because I got another idea: instead of thereduced jobset, we can limit it to x86_64 only. That way we getsubstitutes for developers, but avoid the expensive and often needlessrebuilds on other architectures.
I will be doing that from here on in between freeze cycles.
The other patch was pushed in bb9a99e6571c492d30f95c5b51ead6861d1dc098.
