ACL Policies aren't required to have any `namespace` blocks, and this is
particularly common with the anonymous policy. If a user visits the web UI
without a token already in their local storage and the anonymous policy has no
`namespace` blocks, the UI will hit unhandled exceptions when rendering the
sidebar or jobs page.
Filter for the case where there's no `namespace` block.
Similar to the deployment watcher fix in #14121 - the server code loves these mutable structs so we need to guard access to the struct fields with locks.
Capturing ch := b.capacityChangeCh is sufficient to satisfy the data race detector, but I noticed it was also possible to leak goroutines:
Since the watchCapacity loop is in charge of receiving from capacityChangeCh and exits when stopCh is closed, senders to capacityChangeCh also must exit when stopCh is closed. Otherwise they may block forever if capacityChangeCh is full because it will never be received on again. I did not find evidence of this occurring in my meager smattering of prod goroutine dumps I have laying around, but this isn't surprising as the chan has a buffer of 8096! I would imagine that is sufficient to handle "late" sends and then just get GC'd away when the last reference to the old chan is dropped. This is just additional safety/correctness.
* Handle conflict swith a cas qp on save and create
* Notify error and give them refresh or overwrite options
* Merge conflict missed, resolved
* Mirage fixture
* Integration test
* Bracket closed (thx jai)
* Adjust tests to account for number of variables with auto-conflicter
The HCL parser allows for labels that aren't needed, which makes it easy to
accidentally write a `secure_variable` block that has the intended path as the
label for that block instead of the innner `path` block. This can result in
silent failure to lock down variables if an incorrectly specified block was used
to reduce the scope of capabilities (for example, if another correctly-written
rule allows access to `*`).
We can't detect the extraneous label in the HCL API, but we can detect if we're
missing `path` blocks entirely. Use this to block obvious user errors.
HTTP API consumers that have network line-of-sight to client nodes can connect
directly for a small number of APIs. But in environments where the consumer
doesn't have line-of-sight, there's a long pause waiting for the
`api.ClientConnTimeout` to expire. Warn about this in the API docs so that
authors can avoid the extra timeout.

The List RPCs only checked the ACL for the Prefix argument of the request. Add
an ACL filter to the paginator for the List RPC.
Extend test coverage of ACLs in the List RPC and in the `acl` package, and add a
"deny" capability so that operators can deny specific paths or prefixes below an
allowed path.
Move conflict resolution implementation into the state store with a new Apply RPC.
This also makes the RPC for secure variables much more similar to Consul's KV,
which will help us support soft deletes in a post-1.4.0 version of Nomad.
Reimplement quotas in the state store functions.

This PR changes the use of structs.ConsulMeshGateway to value types
instead of via pointers. This will help in a follow up PR where we
cleanup a lot of custom comparison code with helper functions instead.
