When secure variables are updated, we were adding the update to the
existing quota tracking without first checking whether it was an
update to an existing variable. In that case we need to add/subtract
only the difference between the new and existing quota usage.

- blocked_evals.total_blocked is the number of evals blocked for *any*
reason
- blocked_evals.total_quota_limit is the number of evals blocked by
quota limits, but critically: their resources are *not* counted in the
cpu/memory
The split between OSS/ENT in ACL checks for the Search RPC has a lot
of repeated code that results in merge conflicts. Move most of the
logic into the shared code so that we can call out to thin functions
for ENT checks.

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.
This PR adds support for specifying checks in services registered to
the built-in nomad service provider.
Currently only HTTP and TCP checks are supported, though more types
could be added later.
Fixes#13505
This fixes#13505 by treating reserved_ports like we treat a lot of jobspec settings: merging settings from more global stanzas (client.reserved.reserved_ports) "down" into more specific stanzas (client.host_networks[].reserved_ports).
As discussed in #13505 there are other options, and since it's totally broken right now we have some flexibility:
Treat overlapping reserved_ports on addresses as invalid and refuse to start agents. However, I'm not sure there's a cohesive model we want to publish right now since so much 0.9-0.12 compat code still exists! We would have to explain to folks that if their -network-interface and host_network addresses overlapped, they could only specify reserved_ports in one place or the other?! It gets ugly.
Use the global client.reserved.reserved_ports value as the default and treat host_network[].reserverd_ports as overrides. My first suggestion in the issue, but @groggemans made me realize the addresses on the agent's interface (as configured by -network-interface) may overlap with host_networks, so you'd need to remove the global reserved_ports from addresses shared with a shared network?! This seemed really confusing and subtle for users to me.
So I think "merging down" creates the most expressive yet understandable approach. I've played around with it a bit, and it doesn't seem too surprising. The only frustrating part is how difficult it is to observe the available addresses and ports on a node! However that's a job for another PR.
In OSS we can upsert an allocation without worrying about whether that
alloc is in a namespace that actually exists, but in ENT that upsert
will add to the namespace's quotas. Ensure we're doing so in this
secure variables RPC test to fix the test breaking in the ENT repo.
* Failing test and TODO for wildcard
* Alias the namespace query parameter for Evals
* eval: fix list when using ACLs and * namespace
Apply the same verification process as in job, allocs and scaling
policy list endpoints to handle the eval list when using an ACL token
with limited namespace support but querying using the `*` wildcard
namespace.
* changelog: add entry for #13530
* ui: set namespace when querying eval
Evals have a unique UUID as ID, but when querying them the Nomad API
still expects a namespace query param, otherwise it assumes `default`.

The sidebar navigation tree for the `operator` sub-sub commands is
getting cluttered and we have a new set of commands coming to support
secure variables keyring as well. Move these all under their own
subtrees.
When the `Full` flag is passed for key rotation, we kick off a core
job to decrypt and re-encrypt all the secure variables so that they
use the new key.

We need to track per-namespace storage usage for secure variables even
in Nomad OSS so that a cluster can be seamlessly upgraded from OSS to
ENT without having to re-calculate quota usage.
Provide a hook in the upsert RPC for enforcement of quotas in
ENT. This will be a no-op in Nomad OSS.
This changeset includes some additional unit tests for secure
variables ACL policies, so that we have explicit coverage of edge
cases we're discussing with the UI folks.
