incrementally ingest eval results nix-eval-jobs streams output, unlike hydra-eval-jobs. Now that we've migrated, we can use this to: 1. Use less RAM by avoiding buffering a whole eval's worth of metadata into a Perl string and an array of JSON objects. 2. Make evals latency a bit lower by allowing the queue runner to start ingesting builds faster. Also use the newly-restored constituents support in `nix-eval-jobs` Note, we pass --workers and --max-memory-size to n-e-j Lost in the h-e-j -> n-e-j migration, causing evaluation to always be single threaded and limited to 4GiB RAM. Follow the config settings like h-e-j used to do (via C++ code).

Depends on NixOS/nix-eval-jobs#349 & NixOS#1421. Almost equivalent to NixOS#1425, but with a small change: when having e.g. an aggregate job with a glob that matches nothing, the jobset evaluation is failed now. This was the intended behavior before (hydra-eval-jobset fails hard if an aggregate is broken), the code-path was never reached however since the aggregate was never marked as broken in this case before.
