Add e2e distribution tests

[degray]

Adds vagrant based e2e tests that run every day at 17:00 UTC via github actions.

1. Provisions the vagrant VM (done every time to ensure we have the latest packages)
2. Installs Orchestrator via our interactive install.sh script
3. Runs testsignal (dotnet DLL monitor) within 30s
4. Checks to ensure testsignal existed properly
5. Uninstalls/purges and stops the Orchestrator
6. Destroys the vagrant VM (clean slate next run)

Account that this sends telemetry to is Orchestrator dist e2e

There's a hard 30m timeout on the e2e job in case a parallel run gets stuck somehow (I have seen provisioning of the vagrant VM take 2m or 7m as an example on the same vagrant box)

Uses macos-12 Github Action runner image as that is the only image that supports nested virtualization at the moment. Request to support it on Linux images have so far gone unanswered. See: actions/runner-images#433

Reviewer can remove branch push trigger on the github action before merging. Left there for now so that the reviewer can trigger/try it.
