Daniel Nephin fa32c78429 ca: set the correct SigningKeyID after config update with Vault provider
The test added in this commit shows the problem. Previously the
SigningKeyID was set to the RootCert not the local leaf signing cert.

This same bug was fixed in two other places back in 2019, but this last one was
missed.

While fixing this bug I noticed I had the same few lines of code in 3
places, so I extracted a new function for them.

There would be 4 places, but currently the InitializeCA flow sets this
SigningKeyID in a different way, so I've left that alone for now.

Daniel Nephin c1cb77b829 ca: make test naming consistent
While working on the CA system it is important to be able to run all the
tests related to the system, without having to wait for unrelated tests.
There are many slow and unrelated tests in agent/consul, so we need some
way to filter to only the relevant tests.

This PR renames all the CA system related tests to start with either
`TestCAMananger` for tests of internal operations that don't have RPC
endpoint, or `TestConnectCA` for tests of RPC endpoints. This allows us
to run all the test with:

    go test -run 'TestCAMananger|TestConnectCA' ./agent/consul

The test naming follows an undocumented convention of naming tests as
follows:

    Test[<struct name>_]<function name>[_<test case description>]

I tried to always keep Primary/Secondary at the end of the description,
and _Vault_ has to be in the middle because of our regex to run those
tests as a separate CI job.

You may notice some of the test names changed quite a bit. I did my best
to identify the underlying method being tested, but I may have been
slightly off in some cases.

Daniel Nephin 460f8919c9 ca: make getLeafSigningCertFromRoot safer
As a method on the struct type this would not be safe to call without first checking
c.isIntermediateUsedToSignLeaf.

So for now, move this logic to the CAMananger, so that it is always correct.

Daniel Nephin 64532ef636 ca: fix stored CARoot representation with Vault provider
We were not adding the local signing cert to the CARoot. This commit
fixes that bug, and also adds support for fixing existing CARoot on
upgrade.

Also update the tests for both primary and secondary to be more strict.
Check the SigningKeyID is correct after initialization and rotation.

Daniel Nephin 772d8f7381 ca: clean up unnecessary raft.Apply response checking
In d2ab767fef21244e9fe3b9887ea70fc177912381 raftApply was changed to handle this check in
a single place, instad of having every caller check it. It looks like these few places
were missed when I did that clean up.

This commit removes the remaining resp.(error) checks, since they are all no-ops now.

Daniel Nephin 8240286956 ca: remove state check in secondarySetPrimaryRoots
This function is only ever called from operations that have already acquired the state lock, so checking
the value of state can never fail.

This change is being made in preparation for splitting out a separate type for the secondary logic. The
state can't easily be shared, so really only the expored top-level functions should acquire the 'state lock'.

Daniel Nephin 877094e2fa ca: remove actingSecondaryCA
This commit removes the actingSecondaryCA field, and removes the stateLock around it. This field
was acting as a proxy for providerRoot != nil, so replace it with that check instead.

The two methods which called secondarySetCAConfigured already set the state, so checking the
state again at this point will not catch runtime errors (only programming errors, which we can catch with tests).
In general, handling state transitions should be done on the "entrypoint" methods where execution starts, not
in every internal method.

This is being done to remove some unnecessary references to c.state, in preparations for extracting
types for primary/secondary.

Daniel Nephin cd5f6b2dfb ca: reduce consul provider backend interface a bit
This makes it easier to fake, which will allow me to use the ConsulProvider as
an 'external PKI' to test a customer setup where the actual root CA is not
the root we use for the Consul CA.

Replaces a call to the state store to fetch the clusterID with the
clusterID field already available on the built-in provider.

Daniel Nephin 3173582b75 ca: return an error when secondary fails to initialize
Previously secondaryInitialize would return nil in this case, which prevented the
deferred initialize from happening, and left the CA in an uninitialized state until a config
update or root rotation.

To fix this I extracted the common parts into the delegate implementation. However looking at this
again, it seems like the handling in secondaryUpdateRoots is impossible, because that function
should never be called before the secondary is initialzied. I beleive we can remove some of that
logic in a follow up.

Daniel Nephin 571acb872e ca: extract primaryUpdateRootCA
This function is only run when the CAManager is a primary. Extracting this function
makes it clear which parts of UpdateConfiguration are run only in the primary and
also makes the cleanup logic simpler. Instead of both a defer and a local var we
can call the cleanup function in two places.

Daniel Nephin a65594d8ec ca: rename functions to use a primary or secondary prefix
This commit renames functions to use a consistent pattern for identifying the functions that

This is a step toward eventually creating separate types and moving these methods off of CAManager.

connect: connect CA Roots in the primary datacenter should use a SigningKeyID derived from their local intermediate (#9428)
This fixes an issue where leaf certificates issued in primary
datacenters using Vault as a Connect CA would be reissued very
frequently (every ~20 seconds) because the logic meant to detect root
rotation was errantly triggering.

The hash of the rootCA was being compared against a hash of the
intermediateCA and always failing. This doesn't apply to the Consul
built-in CA provider because there is no intermediate in use in the
primary DC.

This is reminiscent of #6513

Ensure that CA initialization does not block leader election.
After fixing that bug I uncovered a couple more:

Fix an issue where we might try to cross sign a cert when we never had a valid root.
Fix a potential issue where reconfiguring the CA could cause either the Vault or AWS PCA CA providers to delete resources that are still required by the new incarnation of the CA.
