* Allow OCSP to use issuer's RevocationSigAlgo
When an issuer specifies a RevocationSigAlgo, we should largely follow
this for both CRLs and OCSP. However, x/crypto/ocsp lacks support for

* PKI: Add support for signature_bits param to the intermediate/generate api
- Mainly to work properly with GCP backed managed keys, we need to
issue signatures that would match the GCP key algorithm.
- At this time due to https://github.com/golang/go/issues/45990 we
can't issue PSS signed CSRs, as the libraries in Go always request
a PKCS1v15.
- Add an extra check in intermediate/generate that validates the CSR's
signature before providing it back to the client in case we generated
a bad signature such as if an end-user used a GCP backed managed key
with a RSA PSS algorithm.
- GCP ignores the requested signature type and always signs with the
key's algorithm which can lead to a CSR that says it is signed with
a PKCS1v15 algorithm but is actually a RSA PSS signature

* Allow generation of up-to-date delta CRLs
While switching to periodic rebuilds of CRLs alleviates the constant
rebuild pressure on Vault during times of high revocation, the CRL
proper becomes stale. One response to this is to switch to OCSP, but not
every system has support for this. Additionally, OCSP usually requires
connectivity and isn't used to augment a pre-distributed CRL (and is
instead used independently).
By generating delta CRLs containing only new revocations, an existing
CRL can be supplemented with newer revocations without requiring Vault
to rebuild all complete CRLs. Admins can periodically fetch the delta
CRL and add it to the existing CRL and applications should be able to
support using serials from both.
Because delta CRLs are emptied when the next complete CRL is rebuilt, it
is important that applications fetch the delta CRL and correlate it to
their complete CRL; if their complete CRL is older than the delta CRL's
extension number, applications MUST fetch the newer complete CRL to
ensure they have a correct combination.
This modifies the revocation process and adds several new configuration
options, controlling whether Delta CRLs are enabled and when we'll
rebuild it.

* Allow tidy to associate revoked certs, issuers
When revoking a certificate, we need to associate the issuer that signed

performed during CRL building (and still remains so), but when running
without CRL building and with only OCSP, performance will degrade as the
issuer needs to be found each time.
Instead, allow the tidy operation to take over this role, allowing us to
increase the performance of OCSP and CRL in this scenario, by decoupling
issuer identification from CRL building in the ideal case.

* Allow correct importing of certs without CRL KU
When Vault imports certificates without KU for CRLSign, we shouldn't
provision CRLUsage on the backing issuer; otherwise, we'll attempt to
build CRLs and Go will cause us to err out. This change makes it clear
(at issuer configuration time) that we can't possibly support this
operation and hopefully prevent users from running into the more cryptic
Go error.
Note that this does not apply for OCSP EKU: the EKU exists, per RFC 6960
Section 2.6 OCSP Signature Authority Delegation, to allow delegation of
OCSP signing to a child certificate. This EKU is not necessary on the
issuer itself, and generally assumes issuers are allowed to issue OCSP
responses regardless of KU/EKU.

* Allow automatic rebuilding of CRLs
When enabled, periodic rebuilding of CRLs will improve PKI mounts in two
way:
1. Reduced load during periods of high (new) revocations, as the CRL
isn't rebuilt after each revocation but instead on a fixed schedule.
2. Ensuring the CRL is never stale as long as the cluster remains up,
by checking for next CRL expiry and regenerating CRLs before that
happens. This may increase cluster load when operators have large
CRLs that they'd prefer to let go stale, rather than regenerating
fresh copies.
In particular, we set a grace period before expiration of CRLs where,
when the periodic function triggers (about once a minute), we check
upcoming CRL expirations and check if we need to rebuild the CRLs.

serial number (e.g., an intermediate under cross-signing might share the
same number as an external root or an unrelated intermediate).

others issuers CRLs, if they validate this issuer's certificate.

its serial submitted for revocation.
This allows certificates generated with no_store=true to be submitted
for revocation afterwards, given a full copy of the certificate. As a
consequence, all roles can now safely move to no_store=true (if desired
for performance) and revocation can be done on a case-by-case basis.

it must use ECDSAWithSHA256 or equivalent instead of SHA256WithRSA. When

* Allow old certs to be cross-signed
In Vault 1.11, we introduced cross-signing support, but the earlier SKID
field change in Vault 1.10 causes problems: notably, certs created on
older versions of Vault (<=1.9) or outside of Vault (with a different
SKID method) cannot be cross-signed and validated in OpenSSL.
In particular, OpenSSL appears to be unique in requiring a SKID/AKID
match for chain building. If AKID and SKID are present on an otherwise
valid client/parent cert pair and the values are different, OpenSSL will
not build a valid path over those two, whereas most other chain
validation implementations will.
Regardless, to have proper cross-signing support, we really aught to
support copying an SKID. This adds such support to the sign-intermediate
endpoint. Support for the /issue endpoint is not added, as cross-signing
leaf certs isn't generally useful and can accept random SKIDs.

The returned chain on the issuer is presented both for signing request
responses and (if the default issuer) on the /ca_chain path. Overriding
the issuers' automatically constructed chain with a manual_chain allows
removal of the root CA if desired.

* Add cn_validations PKI Role parameter
This new parameter allows disabling all validations on a common name,
enabled by default on sign-verbatim and issuer generation options.
Presently, the default behavior is to allow either an email address
(denoted with an @ in the name) or a hostname to pass validation.
Operators can restrict roles to just a single option (e.g., for email
certs, limit CNs to have strictly email addresses and not hostnames).
By setting the value to `disabled`, CNs of other formats can be accepted
without validating their contents against our minimal correctness checks
for email/hostname/wildcard that we typically apply even when broad
permissions (allow_any_name=true, enforce_hostnames=false, and
allow_wildcard_certificates=true) are granted on the role.

This adds a note that manual_chain is required for cross-signed
intermediates, as Vault will not automatically associate the
cross-signed pair during chain construction. During issuance, the chain
is used verbatim from the issuer, so no chain detection will be used
then.

* Add integration tests for aliased PKI paths (root/rotate, root/replace)
- Add tests for the two api endpoints
- Also return the issuer_name field within the generate root api response
* Add key_name to generate root api endpoint response and doc updates
- Since we are now returning issuer_name, we should also return key_name
- Update the api-docs for the generate root endpoint responses and add
missing arguments that we accept.
* Add a little more information about PKI and replicated data sets.
- Add a TOC to the PKI considerations page
- Merge in the existing certificate storage into a new Replicated DataSets

* PKI - Add not_before_duration API parameter to:
- Root CA generation
- Intermediate CA generation
- Intermediate CA signing
* Move not_before_duration to addCACommonFields
This gets applied on both root generation and intermediate signing,
which is the correct place to apply this.

* Protect against key and issuer name re-use
- While importing keys and issuers verify that the provided name if any has not been used by another key that we did not match against.
- Validate an assumption within the key import api, that we were provided a single key
- Add additional tests on the new key generation and key import handlers.
* Protect key import api end-users from using "default" as a name
- Do not allow end-users to provide the value of default as a name for key imports
as that would lead to weird and wonderful behaviors to the end-user.
* Add missing api-docs for PKI key import
* Begin restructuring FIPS documentation
This creates a new FIPS category under Enterprise and copies the
FIPS-specific seal wrap documentation into it.
We leave the existing Seal Wrap page at the old path, but document that
the FIPS-specific portions of it have moved.

1. To provide an explicit grouping of APIs by user usage and roles,
2. To add all of the new APIs, hopefully with as minimal duplication
as possible.

When adding SignatureBits control logic, we incorrectly allowed
specification of SignatureBits in the case of an ECDSA issuer. As noted
in the original request, NIST and Mozilla (and others) are fairly
prescriptive in the choice of signatures (matching the size of the
NIST P-curve), and we shouldn't usually use a smaller (or worse, larger
and truncate!) hash.
Ignore the configuration of signature bits and always use autodetection
for ECDSA like ed25519.
