Schedule at most 3 builds every 10'

Builds are taking quite some time and we cannot guarantee to run
more than 3 builds every 10 minutes, which translate into 12 parallel
jobs. It is much better to avoid building
up the backlog and leave more builds for the next iteration flow run.

When querying Gerrit we will then need to get the full list of changes
from the past 24h.
