* Seal HA: Use new SealWrappedValue type to abstract seal wrapped values
Introduce SealWrappedValue to abstract seal wrapped values.
Make SealWrappedValue capable of marshalling into a BlobInfo, when there is
plaintext or a single encryption, or to a custom serialization consisting of a
header, length and a marshalled MultiWrapValue protobuf.
* Vault-13769: Support configuring and using multiple seals for unsealing
* Make sealWrapBackend start using multiple seals
* Make seal.Access no longer implement wrapping.Wrapper.
Instead, add the Encrypt and Decrypt methods to the Access interface.
* Make raft snapshot system use funcs SealWrapValue + UnsealWrapValue.
Move the snapshot.Sealer implementation to the vault package to
avoid circular imports.
* Update sealWrapBackend to use multiple seals for encryption.
Use all the encryption wrappers when storing seal wrapped values.
Try do decrypt using the highest priority wrapper, but try all
combinations of encrypted values and wrappers if necessary.
* Allow the use of multiple seals for entropy augmentation
Add seal_name variable in entropy stanza
Add new MultiSourcer to accommodate the new entropy augmentation behavior.
* Individually health check each wrapper, and add a sys/seal-backend-status endpoint.
* Address a race, and also a failed test mock that I didn't catch
* Track partial wrapping failures...
... where one or more but not all access.Encrypts fail for a given write.
Note these failures by adding a time ordered UUID storage entry containing
the path in a special subdirectory of root storage. Adds a callback
pattern to accomplish this, with certain high value writes like initial
barrier key storage not allowing a partial failure. The followup work
would be to detect return to health and iterate through these storage
entries, rewrapping.
* Add new data structure to track seal config generation (#4492)
* Add new data structure to track seal config generation
* Remove import cycle
* Fix undefined variable errors
* update comment
* Update setSeal response
* Fix setSealResponse in operator_diagnose
* Scope the wrapper health check locks individually (#4491)
* Refactor setSeal function in server.go. (#4505)
Refactor setSeal function in server.go.
* Decouple CreateSecureRandomReaderFunc from seal package.
Instead of using a list of seal.SealInfo structs, make
CreateSecureRandomReaderFunc use a list of new EntropySourcerInfo structs. This
brakes the denpency of package configutil on the seal package.
* Move SealGenerationInfo tracking to the seal Access.
* Move SealGenerationInfo tracking to the seal Access.
The SealGenerationInfo is now kept track by a Seal's Access instead of by the
Config object. The access implementation now records the correct generation
number on seal wrapped values.
* Only store and read SealGenerationInfo if VAULT_ENABLE_SEAL_HA_BETA is true.
* Add MultiWrapValue protobuf message
MultiWrapValue can be used to keep track of different encryptions of a value.

* Handle migrations between single-wrapper and multi-wrapper autoSeals
* Extract method SetPhysicalSealConfig.
* Extract function physicalSealConfig.
The extracted function is the only code now reading SealConfig entries from
storage.
* Extract function setPhysicalSealConfig.
The extracted function is the only code now writing SealConfig entries from
storage (except for migration from the old recovery config path).
* Move SealConfig to new file vault/seal_config.go.
* Add SealConfigType quasy-enumeration.
SealConfigType is to serve as the typed values for field SealConfig.Type.
* Rename Seal.RecoveryType to RecoverySealConfigType.
Make RecoverySealConfigType return a SealConfigType instead of a string.
* Rename Seal.BarrierType to BarrierSealConfigType.
Make BarrierSealConfigType return a SealConfigType.
Remove seal.SealType (really a two-step rename to SealConfigType).
* Add Seal methods ClearBarrierConfig and ClearRecoveryConfig.
* Handle autoseal <-> multiseal migrations.
While going between single-wrapper and multiple-wrapper autoseals are not
migrations that require an unwrap seal (such as going from shamir to autoseal),
the stored "barrier" SealConfig needs to be updated in these cases.
Specifically, the value of SealConfg.Type is "multiseal" for autoSeals that have
more than one wrapper; on the other hand, for autoseals with a single wrapper,
SealConfig.Type is the type of the wrapper.
* Remove error return value from NewAutoSeal constructor.
* Automatically rewrap partially seal wrapped values on an interval
* Add in rewrapping of partially wrapped values on an interval, regardless of seal health/status.
* Don't set SealGenerationInfo Rewrapped flag in the partial rewrap call.
* Unexport the SealGenerationInfo's Rewrapped field, add a mutex to it for thread safe access, and add accessor methods for it.
* Add a success callback to the manual seal rewrap process that updates the SealGenerationInfo's rewrapped field. This is done via a callback to avoid an import cycle in the SealRewrap code.
* Fix a failing seal wrap backend test which was broken by the unexporting of SealGenerationInfo's Rewrapped field.
* Nil check the seal rewrap success callback before calling it.
* Change SealGenerationInfo rewrapped parameter to an atomic.Bool rather than a sync.RWMutex for simplicity and performance.
* Add nil check for SealAccess before updating SealGenerationInfo rewrapped status during seal rewrap call.
* Update partial rewrap check interval from 10 seconds to 1 minute.
* Update a reference to SealGenerationInfo Rewrapped field to use new getter method.
* Fix up some data raciness in partial rewrapping.
* Account for possibly nil storage entry when retrieving partially wrapped value.
* Allow multi-wrapper autoSeals to include disabled seal wrappers.
* Restore propagation of wrapper configuration errors by setSeal.
Function setSeal is meant to propagate non KeyNotFound errors returned by calls
to configutil.ConfigureWrapper.
* Remove unused Access methods SetConfig and Type.
* Allow multi-wrapper autoSeals to include disabled seal wrappers.
Make it possible for an autoSeal that uses multiple wrappers to include disabled
wrappers that can be used to decrypt entries, but are skipped for encryption.
e an unwrapSeal when there are disabled seals.
* Fix bug with not providing name (#4580)
* add suffix to name defaults
* add comment
* only change name for disabled seal
* Only attempt to rewrap partial values when all seals are healthy.
* Only attempt to rewrap partial values when all seals are healthy.
* Change logging level from info to debug for notice about rewrap skipping based on seal health.
* Remove stale TODOs and commented out code.

* Move seal barrier type field from Access to autoSeal struct.
Remove method Access.SetType(), which was only being used by a single test, and
which can use the name option of NewTestSeal() to specify the type.
* Change method signatures of Access to match those of Wrapper.
* Turn seal.Access struct into an interface.
* Tweak Access implementation.
Change `access` struct to have a field of type wrapping.Wrapper, rather than
extending it.
* Add method Seal.GetShamirWrapper().
Add method Seal.GetShamirWrapper() for use by code that need to perform
Shamir-specific operations.
* OSS portion of wrapper-v2
* Prefetch barrier type to avoid encountering an error in the simple BarrierType() getter
* Rename the OveriddenType to WrapperType and use it for the barrier type prefetch
* Fix unit test
* Tackle #4929 a different way
This turns c.sealed into an atomic, which allows us to call sealInternal
without a lock. By doing so we can better control lock grabbing when a
condition causing the standby loop to get out of active happens. This
encapsulates that logic into two distinct pieces (although they could
be combined into one), and makes lock guarding more understandable.
* Re-add context canceling to the non-HA version of sealInternal
* Return explicitly after stopCh triggered
