The `Metrics` suite uses prometheus to scrape Nomad metrics so that
we're testing the full user experience of extracting metrics from
Nomad. With the addition of mTLS, we need to make sure prometheus also
has mTLS configuration because the metrics endpoint is protected.
Update the Nomad client configuration and prometheus job to bind-mount
the client's certs into the task so that the job can use these certs
to scrape the server. This is a temporary solution that gets the job
passing; we should give the job its own certificates (issued by
Vault?) when we've done some of the infrastructure rework we'd like.
We have been using fatih/hclfmt which is long abandoned. Instead, switch
to HashiCorp's own hclfmt implementation. There are some trivial changes in
behavior around whitespace.
Adds Windows targets to the client/allocs metrics tests. Removes the
`allocstats` test, which covers less than these tests and is now
redundant.
Adds a firewall rule to our Windows instances so that the prometheus
server can scrape the Nomad HTTP API for metrics.
Refactor the metrics end-to-end tests so they can be run with our e2e
test framework. Runs fabio/prometheus and a collection of jobs that
will cause metrics to be measured. We then query Prometheus to ensure
we're publishing those allocation metrics and some metrics from the
clients as well.
Includes adding a placeholder for running the same tests on Windows.
* Adds a constraint to prevent tests from landing on Windows
* Improve Terraform output for mixed windows/linux clients
* Makes some Windows client config fixes from 0.10.2 testing

facilitate monitoring based off of a logger
