cli: update scaling policy list help to include job flag.

UI: Fix the raw 'blue' in recommendation cards to use '$blue'

The only user of monitor(evalID, true) was command/eval_status, and
eval_status had a duplicate of the prefix-handling code inside it, so in
all cases the complete evalID was being passed to monitor.

Given that, we can remove the prefix code from command/monitor, and
remove the boolean arg.

website: require Node v12

Repurpose dispatch-job capability to dispatch periodic jobs

Co-authored-by: Drew Bailey <2614075+drewbailey@users.noreply.github.com>

This is a first draft of HCLv2 docs - I added the details under hcl2 doc with some minimal info highlighting the hcl2 introductions.

As a longer term strategy, we'll want to mimic the Packer HCL docs structure that details all the blocks and allowed expressions/functions in greater details. However, given that the exact functions and templating syntax is still somewhat influx, I opt to push that to another time.

v12 is currently the default now,
https://vercel.com/docs/runtimes#official-runtimes/node-js/node-js-version,
but we'd rather be explicit about the version we use and ensure that it
matches local development.

Start using Node.js v12.19.0, the most recent active LTS that is
supported by Vercel:
https://vercel.com/docs/runtimes#official-runtimes/node-js/node-js-version
.

The docs now require String.prototype.matchAll, that's part of ES2020
support, and is not available on Node.js 10.x.

changelog entry for https://github.com/hashicorp/nomad/pull/9225

Use alternative test for macOS JVM with /usr/libexec/java_home

This test occasionally fails because the random generation
sometimes produces a node with no allocations, such as here:
https://app.circleci.com/pipelines/github/hashicorp/nomad/12735/workflows/9a407f87-0383-48ee-8e41-7e6e351dce28/jobs/113130/steps

This is a temporary measure to solve it without trying to force the
generated data to always have an allocation.

The `template.allow_host_source` configuration was not operable, leading to
the recent security patch in 0.12.6. We forgot to update this piece of the
documentation referring to the correct configuration value.

This adds support for specifying a global topic match for a specific
key.

UI: Add namespace and task states query params to the topology route

Build configuration files need comments, and JSON is also just the worst, isn't it?
Upgrade our E2E packer configs to use the new HCL2 syntax.

The `nomad_sha`, `nomad_version`, and `nomad_local_binary` variables for the
Nomad provisioning module assumed that only one would be set. By having the
override each other with an explicit precedence, it makes it easier to avoid
problems with Terraform's implicit variables behavior.

Set the expected default values in the `terraform.full.tfvars` to avoid
shadowing by any future changes to the `terraform.tfvars` file.

Update the Makefile to put the `-var` and `-var-file` in the correct order.

alignment-baseline appears to be ignored in Firefox, but dominant-baseline
works. This also moves the anchor into CSS.

This is a few combined iterations on the DAS feature.

* remove unused vault installation from Windows AMI
* match Windows and Linux Consul versions
* bump AMI base Nomad to current stable

UI: Update the warning icon

The base Ubuntu AMI modifies apt sources during cloud-init. But the Packer
build can potentially start the setup script before that work is done,
resulting in errors trying to install base system dependencies like
`dnsmasq`. Delay the setup long enough to lose the race with cloud-init.
