* validate policy against nodes, error if not valid this commit aims to improve the feedback of "runtime" policy errors which would only manifest when the rules are compiled to filter rules with nodes. this change will in; file-based mode load the nodes from the db and try to compile the rules on start up and return an error if they would not work as intended. database-based mode prevent a new ACL being written to the database if it does not compile with the current set of node.

Integration testing
Headscale relies on integration testing to ensure we remain compatible with Tailscale.
This is typically performed by starting a Headscale server and running a test "scenario" with an array of Tailscale clients and versions.
Headscale's test framework and the current set of scenarios are defined in this directory.
Tests are located in files ending with _test.go and the framework are located in the rest.
Running integration tests locally
The easiest way to run tests locally is to use [act](INSERT LINK), a local GitHub Actions runner:
act pull_request -W .github/workflows/test-integration-v2-TestPingAllByIP.yaml
Alternatively, the docker run command in each GitHub workflow file can be used.
Running integration tests on GitHub Actions
Each test currently runs as a separate workflows in GitHub actions, to add new test, run
go generate inside ../cmd/gh-action-integration-generator/ and commit the result.
