In Nomad 1.4.0, we shipped support for encrypted Variables and signed Workload
Identities, but the key material is protected only by a AEAD encrypting the
KEK. Add support for Vault transit encryption and external KMS from major cloud
providers. The servers call out to the external service to decrypt each key in
the on-disk keystore.

Add the plumbing we need to accept multiple Consul clusters in Nomad agent
configuration, to support upcoming Nomad Enterprise features. The `consul` blocks
are differentiated by a new `name` field, and if the `name` is omitted it
becomes the "default" Consul configuration. All blocks with the same name are
merged together, as with the existing behavior.
As with the `vault` block, we're still using HCL1 for parsing configuration and
the `Decode` method doesn't parse multiple blocks differentiated only by a field
name without a label. So we've had to add an extra parsing pass, similar to what
we've done for HCL1 jobspecs. This also revealed a subtle bug in the `vault`
block handling of extra keys when there are multiple `vault` blocks, which I've
fixed here.
For now, all existing consumers will use the "default" Consul configuration, so
there's no user-facing behavior change in this changeset other than the contents
of the agent self API.

Plan rejections occur when the scheduler work and the leader plan
applier disagree on the feasibility of a plan. This may happen for valid
reasons: since Nomad does parallel scheduling, it is expected that
different workers will have a different state when computing placements.
As the final plan reaches the leader plan applier, it may no longer be
valid due to a concurrent scheduling taking up intended resources. In
these situations the plan applier will notify the worker that the plan
was rejected and that they should refresh their state before trying
again.
In some rare and unexpected circumstances it has been observed that
workers will repeatedly submit the same plan, even if they are always
rejected.
While the root cause is still unknown this mitigation has been put in
place. The plan applier will now track the history of plan rejections
per client and include in the plan result a list of node IDs that should
be set as ineligible if the number of rejections in a given time window
crosses a certain threshold. The window size and threshold value can be
adjusted in the server configuration.
To avoid marking several nodes as ineligible at one, the operation is rate
limited to 5 nodes every 30min, with an initial burst of 10 operations.
