* Add ACME TLS-ALPN-01 Challenge validator to PKI
This adds support for verifying the last missing challenge type,
TLS-ALPN-01 challenges, using Go's TLS library. We wish to add this as
many servers (such as Caddy) support transparently renewing certificates
via this protocol, without influencing the contents of sites served.

* Enable suggesting, validating tls-alpn-01 in PKI
Notably, while RFC 8737 is somewhat vague about what identifier types
can be validated with this protocol, it does restrict SANs to be only
DNSSans; from this, we can infer that it is not applicable for IP
typed identifiers. Additionally, since this must resolve to a specific
domain name, we cannot provision it for wildcard identifiers either.

In addition to the standard test cases, we run:

- A test without a DNSSan (bad),
- A test with a bad DNSSan (bad),
- A test with some other SANs (bad),
- A test without a CN (good),
- A test without any leaf (bad), and
- A test without the extension (bad).

* Allow tidy to backup legacy CA bundles
With the new tidy_move_legacy_ca_bundle option, we'll use tidy to move
the legacy CA bundle from /config/ca_bundle to /config/ca_bundle.bak.
This does two things:
1. Removes ca_bundle from the hot-path of initialization after initial
migration has completed. Because this entry is seal wrapped, this
may result in performance improvements.
2. Allows recovery of this value in the event of some other failure
with migration.
Notably, this cannot occur during migration in the unlikely (and largely
unsupported) case that the operator immediately downgrades to Vault
<1.11.x. Thus, we reuse issuer_safety_buffer; while potentially long,
tidy can always be run manually with a shorter buffer (and only this
flag) to manually move the bundle if necessary.
In the event of needing to recover or undo this operation, it is
sufficient to use sys/raw to read the backed up value and subsequently
write it to its old path (/config/ca_bundle).
The new entry remains seal wrapped, but otherwise isn't used within the
code and so has better performance characteristics.
Performing a fat deletion (DELETE /root) will again remove the backup
like the old legacy bundle, preserving its wipe characteristics.

* Allow templating of cluster-local AIA URIs
This adds a new configuration path, /config/cluster, which retains
cluster-local configuration. By extending /config/urls and its issuer
counterpart to include an enable_templating parameter, we can allow
operators to correctly identify the particular cluster a cert was
issued on, and tie its AIA information to this (cluster, issuer) pair
dynamically.
Notably, this does not solve all usage issues around AIA URIs: the CRL
and OCSP responder remain local, meaning that some merge capability is
required prior to passing it to other systems if they use CRL files and
must validate requests with certs from any arbitrary PR cluster.

* Add automatic tidy of expired issuers
To aid PKI users like Consul, which periodically rotate intermediates,
and provided a little more consistency with older versions of Vault
which would silently (and dangerously!) replace the configured CA on
root/intermediate generation, we introduce an automatic tidy of expired
issuers.
This includes a longer safety buffer (1 year) and logging of the
relevant issuer information prior to deletion (certificate contents, key
ID, and issuer ID/name) to allow admins to recover this value if
desired, or perform further cleanup of keys.
From my PoV, removal of the issuer is thus a relatively safe operation
compared to keys (which I do not feel comfortable removing) as they can
always be re-imported if desired. Additionally, this is an opt-in tidy
operation, not enabled by default. Lastly, most major performance
penalties comes with lots of issuers within the mount, not as much
large numbers of keys (as only new issuer creation/import operations are
affected, unlike LIST /issuers which is a public, unauthenticated
endpoint).

* PKI: Add support for signature_bits param to the intermediate/generate api
- Mainly to work properly with GCP backed managed keys, we need to

- 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

In particular, a default tidy configuration is written (via
/config/auto-tidy) which mirrors the options passed to /tidy. Two
additional parameters, enabled and interval, are accepted, allowing
auto-tidy to be enabled or disabled and controlling the interval
(between successful tidy runs) to attempt auto-tidy.
Notably, a manual execution of tidy will delay additional auto-tidy
operations. Status is reported via the existing /tidy-status endpoint.
