* Store jobset evaluations in the database explicitly. This includes

Browse source 
recording the builds that are part of a jobset evaluation.  We need
  this to be able to answer queries such as "return the latest NixOS
  ISO for which the installation test succeeded".  This wasn't previously
  possible because the database didn't record which builds of (say)
  the `isoMinimal' job and the `tests.installer.simple' job came from
  the same evaluation of the nixos:trunk jobset.

  Keeping a record of evaluations is also useful for logging purposes.
