* Rename Intermediate cert references to LeafSigningCert
Within the Consul CA subsystem, the term "Intermediate"
is confusing because the meaning changes depending on
provider and datacenter (primary vs secondary). For
example, when using the Consul CA the "ActiveIntermediate"
may return the root certificate in a primary datacenter.
At a high level, we are interested in knowing which
CA is responsible for signing leaf certs, regardless of
its position in a certificate chain. This rename makes
the intent clearer.
* Move provider state check earlier
* Remove calls to GenerateLeafSigningCert
GenerateLeafSigningCert (formerly known
as GenerateIntermediate) is vestigial in
non-Vault providers, as it simply returns
the root certificate in primary
datacenters.
By folding Vault's intermediate cert logic
into `GenerateRoot` we can encapsulate
the intermediate cert handling within
`newCARoot`.
* Move GenerateLeafSigningCert out of PrimaryProvidder
Now that the Vault Provider calls
GenerateLeafSigningCert within
GenerateRoot, we can remove the method
from all other providers that never
used it in a meaningful way.
* Add test for IntermediatePEM
* Rename GenerateRoot to GenerateCAChain
"Root" was being overloaded in the Consul CA
context, as different providers and configs
resulted in a single root certificate or
a chain originating from an external trusted
CA. Since the Vault provider also generates
intermediates, it seems more accurate to
call this a CAChain.
All of the current integration tests where Vault is the Connect CA now use non-root tokens for the test. This helps us detect privilege changes in the vault model so we can keep our guides up to date.
One larger change was that the RenewIntermediate function got refactored slightly so it could be used from a test, rather than the large duplicated function we were testing in a test which seemed error prone.
The fix outlined and merged in #15253 fixed the issue as it occurs in the primary
DC. There is a similar issue that arises when vault is used as the Connect CA in a
secondary datacenter that is fixed by this PR.
Additionally: this PR adds support to run the existing suite of vault related integration
tests against the last 4 versions of vault (1.9, 1.10, 1.11, 1.12)

Previously we had a couple copies that reproduced the FSM operation.
These copies introduce risk that the test does not accurately match
production.
This PR removes the test versions of the FSM operation, and exports the
real production FSM operation so that it can be used in tests.
The consul provider tests did need to change because of this. Previously
we would return a hardcoded value of 2, but in production this value is
always incremented.
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.

As part of this change, we ensure that the SAN extensions are marked as
critical when the subject is empty so that AWS PCA tolerates the loss of
common names well and continues to function as a Connect CA provider.
Parts of this currently hack around a bug in crypto/x509 and can be
removed after https://go-review.googlesource.com/c/go/+/329129 lands in
a Go release.
Note: the AWS PCA tests do not run automatically, but the following
passed locally for me:
ENABLE_AWS_PCA_TESTS=1 go test ./agent/connect/ca -run TestAWS
Add a skip condition to all tests slower than 100ms.
This change was made using `gotestsum tool slowest` with data from the
last 3 CI runs of master.

Currently when using the built-in CA provider for Connect, root certificates are valid for 10 years, however secondary DCs get intermediates that are valid for only 1 year. There is no mechanism currently short of rotating the root in the primary that will cause the secondary DCs to renew their intermediates.
This PR adds a check that renews the cert if it is half way through its validity period.
In order to be able to test these changes, a new configuration option was added: IntermediateCertTTL which is set extremely low in the tests.
* Change CA Configure struct to pass Datacenter through
* Remove connect/ca/plugin as we don't have immediate plans to use it.
We still intend to one day but there are likely to be several changes to the CA provider interface before we do so it's better to rebuild from history when we do that work properly.
* Rename PrimaryDC; fix endpoint in secondary DCs
* pass logger through to provider
* test for proper operation of NeedsLogger

The fields in the certs are meant to hold the original binary
representation of this data, not some ascii-encoded version.
The only time we should be colon-hex-encoding fields is for display
purposes or marshaling through non-TLS mediums (like RPC).
All these changes should have no side-effects or change behavior:
- Use bytes.Buffer's String() instead of a conversion
- Use time.Since and time.Until where fitting
- Drop unnecessary returns and assignment
* Fix CA pruning when CA config uses string durations.
The tl;dr here is:
- Configuring LeafCertTTL with a string like "72h" is how we do it by default and should be supported
- Most of our tests managed to escape this by defining them as time.Duration directly
- Out actual default value is a string
- Since this is stored in a map[string]interface{} config, when it is written to Raft it goes through a msgpack encode/decode cycle (even though it's written from server not over RPC).
- msgpack decode leaves the string as a `[]uint8`
- Some of our parsers required string and failed
- So after 1 hour, a default configured server would throw an error about pruning old CAs
- If a new CA was configured that set LeafCertTTL as a time.Duration, things might be OK after that, but if a new CA was just configured from config file, intialization would cause same issue but always fail still so would never prune the old CA.
- Mostly this is just a janky error that got passed tests due to many levels of complicated encoding/decoding.
tl;dr of the tl;dr: Yay for type safety. Map[string]interface{} combined with msgpack always goes wrong but we somehow get bitten every time in a new way :D
We already fixed this once! The main CA config had the same problem so @kyhavlov already wrote the mapstructure DecodeHook that fixes it. It wasn't used in several places it needed to be and one of those is notw in `structs` which caused a dependency cycle so I've moved them.
This adds a whole new test thta explicitly tests the case that broke here. It also adds tests that would have failed in other places before (Consul and Vaul provider parsing functions). I'm not sure if they would ever be affected as it is now as we've not seen things broken with them but it seems better to explicitly test that and support it to not be bitten a third time!
* Typo fix
* Fix bad Uint8 usage
