This is implement in an extremely hacky way due to poor DBIx feature
support. Ideally, what we'd need is a way to tell DBIx to ignore the
errormsg column unless explicitly requested, and to automatically add a
computed 'errormsg IS NULL' column in others. Since it does not support
that, this commit instead hacks some support via method overrides while
taking care to not break anything obvious.
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).
`nix-eval-jobs` should check `hydraJobs` and then `checks` with flakes

I have not experienced regressions with local testing.
(cherry picked from commit 4b886d9c45cd2d7fe9b0a8dbc05c7318d46f615d)
In 1bd195a5138b3c69c52110d713c706cb4908ba16 strictDeps was set for the
Hydra package. As a result, `checkInputs` aren't available anymore in
the local dev-shell which is the sole purpose of foreman, to start
services and a database for development.
