[libvirt PATCH 0/4] ci: reduce number of jobs in the pipeline

[Daniel P. Berrangé]

Come June 1st (aka very very soon) GitLab will reduce the
CI minutes quota available from 2000 to 400 for public
projects.

The wallclock minutes for CI are the quota divided by
a cost factor currently 0.008. IOW, after June 1st
our allowance reduces from 250,000 wallclock minutes
to 50,000.

While I had intended that we join the OSS program, I'm
unhappy with the financial liability the T&Cs require
us to agree to for tha

Usage stats show we're currently consuming 70-80,000
minutes a month, so we need to cut our usage by at
least 30%.

The main libvirt project is responsible for the vast
majority of usage, so is the biggest quick win, but
we need to economise across all our repos.

With this series, we increase the number of jobs in
the pipeline from 82 to 100, but we mark a great many
of them as manual jobs, so they never run unless a
user explicitly triggers them.

So we have only 54 jobs executing instead of the
original 82. The remaining 46 jobs are optional.
This is a decent win in usage, but we probably need
to cut a little more later to give us breathing space
