Based off the existing GithubPulls.pm and GitlabPulls.pm plugins.
Also adds an integration test for the new 'giteapulls' input type to
the existing 'gitea' test.
Needed one more thing before trying out using `LegacySSHStore` directly.
Flake lock file updates:
• Updated input 'nix':
'github:NixOS/nix/674a87462cb93f605d4fbeef607d3453e7e5a7d8?narHash=sha256-TBoHqnIdVWhsBcL05vO2B1hSl9m//5Mz2NU%2BPMk3h3Y%3D' (2025-02-16)

This avoids some duplicated code, leveraging the same `StoreReference`
type that also undergirds the machine file dedup we just did prior.
By using `LegacySSHStoreConfig`, we're also taking a baby step towards
using the store interface rather than messing around with the protocol
internals.
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

It seemed there was no self-contained end-to-end test actually doing
this?!
Among other things, this will help ensure that the switch-over to
`nix-eval-jobs` is correct.
Just ordering yourself after network-online.target will not guarantee
that it will be loaded. You'll have to either want or require it. Hence
the following trace on recent nixpkgs versions:
evaluation warning: hydra-queue-runner.service is ordered after 'network-online.target' but doesn't depend on it
* Update version in example
* Update docs to fix invalid indentifier when using 'hello'
* fix build issue for hello example

I have not experienced regressions with local testing.

When people reach out to the git repository they probably want to use
hydra from the same source.
This also removes the need for an overlay with simpler and more
performant direct use of the nixpkgs passed in. Before it was
re-importing nixpkgs.
test
There is an overlay for the `hydra` name, but `hydra_unstable` was used, which can refer to the nixpkgs package and lead to and outdated hydra version and requires configuring the correct package attribute downstream.
In my system logs I see this every time a new eval starts:
```
hydra-evaluator[PID]: hint: Using 'master' as the name for the initial branch. This default branch name
hydra-evaluator[PID]: hint: is subject to change. To configure the initial branch name to use in all
hydra-evaluator[PID]: hint: of your new repositories, which will suppress this warning, call:
hydra-evaluator[PID]: hint:
hydra-evaluator[PID]: hint: git config --global init.defaultBranch <name>
hydra-evaluator[PID]: hint:
hydra-evaluator[PID]: hint: Names commonly chosen instead of 'master' are 'main', 'trunk' and
hydra-evaluator[PID]: hint: 'development'. The just-created branch can be renamed via this command:
hydra-evaluator[PID]: hint:
hydra-evaluator[PID]: hint: git branch -m <name>
```
This ensures this hint is not logged anymore and unclutters the syslog.
I presume it does not really matter what name is chosen for the branch.
