Break grabLockOrStop into two pieces to facilitate investigating deadlocks. Without this change, the "grab" goroutine looks the same regardless of who was calling grabLockOrStop, so there's no way to identify one of the deadlock parties.
OSS parts of ent PR #3172: assume nodes we haven't received heartbeats from are running the same version as we are. Failing to provide a version/upgrade_version will result in Autopilot (on ent) demoting those unversioned nodes to non-voters until we receive a heartbeat from them.

* storage/raft: Fix cluster init with retry_join
Commit 8db66f4853abce3f432adcf1724b1f237b275415 introduced an error
wherein a join() would return nil (no error) with no information on its
channel if a joining node had been initialized. This was not handled
properly by the caller and resulted in a canceled `retry_join`.
Fix this by handling the `nil` channel respone by treating it as an
error and allowing the existing mechanics to work as intended.
* storage/raft: Improve retry_join go test
* storage/raft: Make VerifyRaftPeers pollable
* storage/raft: Add changelog entry for retry_join fix
* storage/raft: Add description to VerifyRaftPeers
* storage/raft: Make raftInfo atomic
This fixes some racy behavior discovered in parallel testing. Change the
core struct member to an atomic and update references throughout.
* raft: Ensure init before setting suffrage
As reported in https://hashicorp.atlassian.net/browse/VAULT-6773:
The /sys/storage/raft/join endpoint is intended to be unauthenticated. We rely
on the seal to manage trust.
It’s possible to use multiple join requests to switch nodes from voter to
non-voter. The screenshot shows a 3 node cluster where vault_2 is the leader,
and vault_3 and vault_4 are followers with non-voters set to false. sent two
requests to the raft join endpoint to have vault_3 and vault_4 join the cluster
with non_voters:true.
This commit fixes the issue by delaying the call to SetDesiredSuffrage until after
the initialization check, preventing unauthenticated mangling of voter status.
Tested locally using
https://github.com/hashicorp/vault-tools/blob/main/users/ncabatoff/cluster/raft.sh
and the reproducer outlined in VAULT-6773.
* raft: Return join err on failure
This is necessary to correctly distinguish errors returned from the Join
workflow. Previously, errors were being masked as timeouts.
* raft: Default autopilot parameters in teststorage
Change some defaults so we don't have to pass in parameters or set them
in the originating tests. These storage types are only used in two
places:
1) Raft HA testing
2) Seal migration testing
Both consumers have been tested and pass with this change.
* changelog: Unauthn voter status change bugfix
* add func to set level for specific logger
* add endpoints to modify log level
* initialize base logger with IndependentLevels
* test to ensure other loggers remain unchanged
* add DELETE loggers endpoints to revert back to config
* add API docs page
* add changelog entry
* remove extraneous line
* add log level field to Core struct
* add godoc for getLogLevel
* add some loggers to c.allLoggers
* fix raft tls key rotation panic when rotation time in past
* add changelog entry
* push out next raft TLS rotation time in case close to elapsing
* consolidate tls key rotation duration calculation
* reduce raft getNextRotationTime padding to 10 seconds
* move tls rotation ticker reset to where its duration is calculated
* See what it looks like to replace "master key" with "root key". There are two places that would require more challenging code changes: the storage path `core/master`, and its contents (the JSON-serialized EncodedKeyringtructure.)
* Restore accidentally deleted line
* Add changelog
* Update root->recovery
* Fix test

* Auto-join support for IPv6 discovery
The go-discover library returns IP addresses and not URLs. It just so
happens net.URL parses "127.0.0.1", which isn't a valid URL.
Instead, we construct the URL ourselves. Being careful to check if it's
an ipv6 address and making sure it's in explicit form if so.
Fixes#12323
* feedback: addrs & ipv6 test
Rename addrs to clusterIPs to improve clarity and intent
Tighten up our IPv6 address detection to be more correct and to ensure
it's actually in implicit form
