Bump github.com/hashicorp/raft from 1.4.0 to 1.6.0

[dependabot]

Bumps github.com/hashicorp/raft from 1.4.0 to 1.6.0.

Release notes

Sourced from github.com/hashicorp/raft's releases.

1.6.0 (November 15th, 2023)

CHANGES

• Upgrade hashicorp/go-msgpack to v2, with go.mod upgraded from v0.5.5 to v2.1.1. GH-577

  go-msgpack v2.1.1 is by default binary compatible with v0.5.5 ("non-builtin" encoding of time.Time), but can decode messages produced by v1.1.5 as well ("builtin" encoding of time.Time).

  However, if users of this libary overrode the version of go-msgpack (especially to v1), this could break compatibility if raft nodes are running a mix of versions.

  This compatibility can be configured at runtime in Raft using NetworkTransportConfig.MsgpackUseNewTimeFormat -- the default is false, which maintains compatibility with go-msgpack v0.5.5, but if set to true, will be compatible with go-msgpack v1.1.5.

IMPROVEMENTS

• Push to notify channel when shutting down. GH-567
• Add CommitIndex API GH-560
• Document some Apply error cases better GH-561

BUG FIXES

• Race with candidateFromLeadershipTransfer GH-570

v1.5.0

Fixes a performance bug related to pipelining. See hashicorp/raft#541 for extensive details on the testing done.

Change in Default Behavior: This is being released as a minor version even though it changes the default behaviour of the library. The rationale for that is that in almost all cases we are aware of (including all HashiCorp tools) the previous behavior performs significantly worse than the new default. Most other users of this library are most likely to notice no change, or see a significant improvement in latency under high load so we want that to be the default experience rather than one that needs tuning to acheive.

It's possible if you are using this library in way that is significantly different to our typical usage (e.g. over very high latency networks and with enough throughput) that this could cause an increase in commit latency. The increase should never exceed the round-trip-time between your servers. The issue being fixed could cause latency increases in the order of 100x more than the mean commit time at high load. If you are still unsure, the old behavior can be retained by setting the new NetTransportConfig.MaxRPCsInFlight = 130.

See the PR for more analysis of this tradeoff.
