Shamir seals now come in two varieties: legacy and new-style. Legacy
Shamir is automatically converted to new-style when a rekey operation
is performed. All new Vault initializations using Shamir are new-style.
New-style Shamir writes an encrypted master key to storage, just like
AutoUnseal. The stored master key is encrypted using the shared key that
is split via Shamir's algorithm. Thus when unsealing, we take the key
fragments given, combine them into a Key-Encryption-Key, and use that
to decrypt the master key on disk. Then the master key is used to read
the keyring that decrypts the barrier.
Generalization of the PhysicalFactory notion introduced by Raft, so it can be used by other storage backends in tests. These are the OSS changes needed for my rework of the ent integ tests and cluster helpers.
There are a few different things happening in this change. First, some code that previously lived in enterprise has moved here: this includes some helper code for manipulating clusters and for building storage backends. Second, the existing cluster-building code using inmem storage has been generalized to allow various storage backends. Third, added support for creating two-cluster DR setups. Finally, there are tweaks to handle edge cases that
result in intermittent failures, or to eliminate sleeps in favour of polling to detect state changes.
Also: generalize TestClusterOptions.PhysicalFactory so it can be used either
as a per-core factory (for raft) or a per-cluster factory (for other
storage backends.)
