Move version out of SDK. (#14229)
Move version out of SDK.  For now it's a copy rather than move: the part not addressed by this change is sdk/helper/useragent.String, which we'll want to remove in favour of PluginString.  That will have to wait until we've removed uses of useragent.String from all builtins.

Create global quotas of each type in every NewTestCluster. (#18038)
Create global quotas of each type in every NewTestCluster.  Also switch some key locks to use DeadlockMutex to make it easier to discover deadlocks in testing.

NewTestCluster also now starts the cluster, and the Start method becomes a no-op.  Unless SkipInit is provided, we also wait for a node to become active, eliminating the need for WaitForActiveNode.  This was needed because otherwise we can't safely make the quota api call.  We can't do it in Start because Start doesn't return an error, and I didn't want to begin storing the testing object T instead TestCluster just so we could call t.Fatal inside Start. 

The last change here was to address the problem of how to skip setting up quotas when creating a cluster with a nonstandard handler that might not even implement the quotas endpoint.  The challenge is that because we were taking a func pointer to generate the real handler func, we didn't have any way to compare that func pointer to the standard handler-generating func http.Handler without creating a circular dependency between packages vault and http.  The solution was to pass a method instead of an anonymous func pointer so that we can do reflection on it.

Plugins: Tighten requirements for multiplexing (#17403)
Change the multiplexing key to use all `PluginRunner` config (converted to a struct which is comparable), so that plugins with the same name but different env, args, types, versions etc are not incorrectly multiplexed together.

Add ability to perform automatic tidy operations (#16900)
* Add ability to perform automatic tidy operations

This enables the PKI secrets engine to allow tidy to be started
periodically by the engine itself, avoiding the need for interaction.
This operation is disabled by default (to avoid load on clusters which
don't need tidy to be run) but can be enabled.

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.

* Prevent race during parallel testing

We modified the RollbackManager's execution window to allow more
faithful testing of the periodicFunc. However, the TestAutoRebuild and
the new TestAutoTidy would then race against each other for modifying
the period and creating their clusters (before resetting to the old
value).

This changeset adds a lock around this, preventing the races.

* Use tidyStatusLock to gate lastTidy time

* Add read lock around tidyStatus gauges

When reading from tidyStatus for computing gauges, since the underlying
values aren't atomics, we really should be gating these with a read lock
around the status access.

Enable periodic, automatic rebuilding of CRLs (#16762)
* 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.

* Allow modification of rollback period for testing

When testing backends that use the periodic func, and specifically,
testing the behavior of that periodic func, waiting for the usual 1m
interval can lead to excessively long test execution. By switching to a
shorter period--strictly for testing--we can make these tests execute
faster.

Remove deprecated call to BuildNameToCertificate (#13811)
This function call was previously used to generate mappings from
potential subjects (or SANs) to certificates within the TLS client
object. However, newer Go versions have deprecated this method, instead
building the mapping automatically based on present certificates at
request time. Because the corresponding client configuration field is
not used in Vault (NameToCertificate), it is safe to remove this call
and leave it nil.

Make TestActivityLog_MultipleFragmentsAndSegments timeout on its own (#11490)
* The main driver for this change was to make the read from a.newFragmentCh timeout quickly rather than waiting for the test timeout (much longer).  While testing the change I observed a panic during shutdown, but it was swallowed and moreover there was no stack trace so it wasn't obvious.  I'm hoping we can get rid of the recover, so I fixed the issue in the activitylog tests that needed it.
