We note that:
- allow_bare_domains, allow_glob_domains, and allow_subdomains are all
independent,
- enforce_hostnames and allow_wildcard_certificates take precedence over
allow_any_name,
- We limit to RFC 6125 wildcards.
- Clarify that both allow_bare_domains and allow_glob_domains will permit
wildcard issuance in certain scenarios.

* Add new AllowWildcardCertificate field to PKI role
This field allows the PKI role to control whether or not issuance of
wildcard certificates are allowed. We default (both on migration and
new role creation) to the less secure true value for backwards
compatibility with existing Vault versions.

* Refactor sanitizedName to reducedName
Per comment, this variable name was confusing during the reproduction
and subsequent fix of the earlier vulnerability and associated bug
report. Because the common name isn't necessarily _sanitized_ in any way
(and indeed must be considered in relation to other parts or the whole),
but portions of the entire name are removed, reducedName appears to make
the most sense.

* Enforce AllowWildcardCertificates during issuance
This commit adds the bulk of correctly validating wildcard certificate
Common Names during issuance according to RFC 6125 Section 6.4.3
semantics. As part of this, support for RFC 2818-conforming wildcard
certificates (wherein there are almost no restrictions on issuance) has
been removed.
Note that this flag does take precedence over AllowAnyName, giving a
little more safety in wildcard issuance in this case.

* Update test cases to conform with RFC 6125
Test cases 19, 70+71, and 83+84 didn't conform with the RFC 6125, and so
should've been rejected under strict conformance. For 70+71 and 83+84,
we previously conditioned around the value of AllowSubdomains (allowing
issuance when true), but they likely should've been rejected either way.
Additionally, update the notes about globs matching wildcard
certificates to notate this is indeed the case.

* Check AllowWildcardCertifciates in issuance tests
This allows for regression tests to cover the new
AllowWildcardCertificate conditional. We add additional test cases
ensuring that wildcard issuance is properly forbidden in all relevant
scenarios, while allowing the existing test cases to validate that
wildcard status doesn't affect non-wildcard certificates.

* Allow issuance of wildcard via glob match
From Vault v1.8.0 onwards, we would incorrectly disallow issuance of a
wildcard certificate when allow_glob_domain was enabled with a
multi-part glob domain in allowed_domains (such as *.*.foo) when
attempting to issue a wildcard for a subdomain (such as *.bar.foo).
This fixes that by reverting an errant change in the case insensitivity
patch. Here, when validating against a very powerful glob construct, we
leave the wildcard prefix (*.) from the raw common_name element, to
allow multi-part globs to match wildcard entries.
It is important to note that "sanitizedName" is an incorrect variable
naming here. Wildcard parsing (per RFC 6125 which supercedes RFC 2818)
must be in the left-most segment of the domain, but we lack validation
to ensure no internal wildcards exist. Additionally per item 3 of
section 6.4.3 of RFC 6125, wildcards MAY be internal to a domain
segment, in which case sanitizedName again leaves the wildcard in place.

* Remove duplicate email address check
As pointed out by Steven Clark (author of the removed conditional in
70012cd865b3dcdab376dba0c0e0abc88c48f508), this is duplicate from the
now-reintroduced comparison against name (versus the erroneous
sanitizedName at the time of his commit).
This is a reversion of the changes to builtin/logical/pki/cert_util.go,
but keeping the additional valuable test cases.

* Add multi-dimensional PKI role issuance tests
This commit introduces multi-dimensional testing of PKI secrets engine's
role-based certificate issuance with the intent of preventing future
regressions.
Here, dimensions of testing include:
- AllowedDomains to decide which domains are approved for issuance,
- AllowBareDomains to decide if raw entries of AllowedDomains are
permitted,
- AllowGlobDomains to decide if glob patterns in AllowedDomains are
parsed,
- AllowSubdomains to decide if subdomains of AllowedDomains are
permitted,
- AllowLocalhost to decide if localhost identifiers are permitted, and
- CommonName of the certificate to request.

* add Core.ShutdownWait that doesn't return until shutdown is done
* create the usedCodes cache on seal and nil it out on pre-seal so that the finalizer kills the janitor goroutine
* stop seal health checks on seal rather than wait for them to discover the active context is done
* make sure all lease-loading goroutines are done before returning from restore
* make uniquePoliciesGc discover closed quitCh immediately instead of only when the ticker fires
* make sure all loading goroutines are done before returning from loadEntities, loadCachedEntitiesOfLocalAliases

* Add checks for other error types within the PKI plugin
- The PKI plugin assumes the code it is calling always returns an error
of type errutil.UserError or errutil.InternalError. While I believe
so far this is still true, it would be easy to add a code path that
just returns a generic error and we would completely ignore it.
- This was found within some managed key testing where I forgot to wrap
an error within one of the expected types
* Add changelog
* Allow OpenSSH-style key type identifiers
To bring better parity with the changes of #14008, wherein we allowed
OpenSSH-style key identifiers during generation. When specifying a list
of allowed keys, validate against both OpenSSH-style key identifiers
and the usual simplified names as well ("rsa" or "ecdsa"). Notably, the
PKI secrets engine prefers "ec" over "ecdsa", so we permit both as well.

* Use rsa-sha2-256 as the default SSH CA hash algo
As mentioned in the OpenSSH 8.2 release notes, OpenSSH will no longer be
accepting ssh-rsa signatures by default as these use the insecure SHA-1
algorithm.
For roles in which an explicit signature type wasn't specified, we
should change the default from SHA-1 to SHA-256 for security and
compatibility with modern OpenSSH releases.
