Renames all variables for acl.Authorizer to use `authz`. Previously some
places used `rule` which I believe was an old name carried over from the
legacy ACL system.
A couple places also used authorizer.
This commit also removes another couple of authorizer nil checks that
are no longer necessary.

The constructor for Server is not at all the appropriate place to be setting default
values for a config struct that was passed in.
In production this value is always set from agent/config. In tests we should set the
default in a test helper.
This field has been unnecessary for a while now. It was always set to the same value
as PrimaryDatacenter. So we can remove the duplicate field and use PrimaryDatacenter
directly.
This change was made by GoLand refactor, which did most of the work for me.
This method suffered from similar naming to a couple other methods on Server, and had not great
re-use (2 callers). By copying a few of the lines into one of the callers we can move the
implementation into the second caller.
Once moved, we can see that ResolveTokenAndDefaultMeta is identical in both Client and Server, and
likely should be further refactored, possibly into ACLResolver.
This change is being made to make ACL resolution easier to trace.
This method was an alias for ACLResolver.ResolveTokenToIdentityAndAuthorizer. By removing the
method that does nothing the code becomes easier to trace.
ACL filtering only needs an authorizer and a logger. We can decouple filtering from
the ACLResolver by passing in the necessary logger.
This change is being made in preparation for moving the ACLResolver into an acl package
filterACLWithAuthorizer could never return an error. This change moves us a little bit
closer to being able to enable errcheck and catch problems caused by unhandled error
return values.
These functions are moved to the one place they are called to improve code locality.
They are being moved out of agent/consul/acl.go in preparation for moving
ACLResolver to an acl package.
These functions are used in only one place. Move the functions next to their one caller
to improve code locality.
This change is being made in preparation for moving the ACLResolver into an
acl package. The moved functions were previously in the same file as the ACLResolver.
By moving them out of that file we may be able to move the entire file
with fewer modifications.

Previously we were passing an Authorizer that would always allow the
operation, then later checking the authorization using vetServiceTxnOp.
On the surface this seemed strange, but I think it was actually masking
a bug as well. Over time `servicePreApply` was changed to add additional
authorization for `service.Proxy.DestinationServiceName`, but because
we were passing a nil Authorizer, that authorization was not handled on
the txn_endpoint.
`TxnServiceOp.FillAuthzContext` has some special handling in enterprise,
so we need to make sure to continue to use that from the Txn endpoint.
This commit removes the `vetServiceTxnOp` function, and passes in the
`FillAuthzContext` function so that `servicePreApply` can be used by
both the catalog and txn endpoints. This should be much less error prone
and prevent bugs like this in the future.

Move the check for the Intention.DestinationName into the Authorizer to remove the
need to check what kind of Authorizer is being used.
It sounds like this check is only for legacy ACLs, so is probably just a safeguard
.
1. do not emit the metric if Query fails
2. properly check for PrimaryUsersIntermediate, the logic was inverted
Also improve the logging by including the metric name in the log message

These checks were a bit more involved. They were previously skipping some code paths
when the authorizer was nil. After looking through these it seems correct to remove the
authz == nil check, since it will never evaluate to true.
These case are already impossible conditions, because most of these functions already start
with a check for ACLs being disabled. So the code path being removed could never be reached.
The one other case (ConnectAuthorized) was already changed in a previous commit. This commit
removes an impossible branch because authz == nil can never be true.
These methods are no longer used. Remove the methods, and update the
tests to use actual method used by production code.
Also removes the 'authz == nil' check is no longer a possible code path
now that we are returning a non-nil acl.Authorizer when ACLs are disabled.
The blocking query backend sets the default value on the server side.
The streaming backend does not using blocking queries, so we must set the timeout on
the client.
Now that we have at least one endpoint that uses context for cancellation we can
encounter this scenario where the returned error is a context.Cancelled or
context.DeadlineExceeded.
If the request.Context().Err() is not nil, then we know the request itself was cancelled, so
we can log a different message at Info level, instad of the error.
Knowing that blocking queries are firing does not provide much
information on its own. If we know the correlation IDs we can
piece together which parts of the snapshot have been populated.
Some of these responses might be empty from the blocking
query timing out. But if they're returning quickly I think we
can reasonably assume they contain data.

If multiple instances of a service are co-located on the same node then
their proxies will all share a cache entry for their resolved service
configuration. This is because the cache key contains the name of the
watched service but does not take into account the ID of the watching
proxies.
This means that there will be multiple agent service manager watches
that can wake up on the same cache update. These watchers then
concurrently modify the value in the cache when merging the resolved
config into the local proxy definitions.
To avoid this concurrent map write we will only delete the key from
opaque config in the local proxy definition after the merge, rather
than from the cached value before the merge.
This change adds a new `dns_config.recursor_strategy` option which
controls how Consul queries DNS resolvers listed in the `recursors`
config option. The supported options are `sequential` (default), and
`random`.

A previous commit used SetHash on two of the cases to fix a data race. This commit applies
that change to all cases. Using SetHash in this test helper should ensure that the
test helper behaves closer to production.
These changes ensure that the identity of services dialed is
cryptographically verified.
For all upstreams we validate against SPIFFE IDs in the format used by
Consul's service mesh:
spiffe://<trust-domain>/ns/<namespace>/dc/<datacenter>/svc/<service>
The dnsConfig pulled from the atomic.Value is a pointer, so modifying it in place
creates a data race. Use the exported ReloadConfig interface instead.
The LogOutput io.Writer used by TestAgent must allow concurrent reads and writes, and a
bytes.Buffer does not allow this. The bytes.Buffer must be wrapped with a lock to make this safe.
Some global variables are patched to shorter values in these tests. But the goroutines that read
them can outlive the test because nothing waited for them to exit.
This commit adds a Wait() method to the routine manager, so that tests can wait for the goroutines
to exit. This prevents the data race because the 'reset to original value' can happen
after all other goroutines have stopped.
A previous commit started using QueryRefuced, but that is not correct. QueryRefuced refers to
the OpCode, not the query type.
Instead use errNoAnswer because we have no records for that query type.
