PR #11550 changed the job stop exit behaviour when monitoring the
deployment. When stopping a job, the deployment becomes cancelled
and therefore the CLI now exits with status code 1 as it see this
as an error.
This change adds a new utility e2e function that accounts for this
behaviour.
After submitting an update, the test ought to wait until the new
allocations are placed. Previously, we'd use the original to-be-stopped
allocations and the test fails when attempting to exec.
Until we have LCOW support in the E2E environment (which requires a Windows
2019 test target), we need to constrain E2E tests to the appropriate kernel
The E2E framework wraps testify's `require` so that by default we can stop
tests on errors, but the cleanup functions should use `assert` so that we
continue to try to cleanup the test environment even if there's a failure.
Exercises host volume and Docker volume functionality for the `exec` and `docker`
task driver, particularly around mounting locations within the container and
how this can be used with `template`.
