And set the `time.Time` option to use the go-msgpack-1.1.5-compatible encoding in all the places, since that is the (now previous) version in `go.mod`. v2 2.1.1 was specifically designe to honor backwards compatibility with 1.1.5 and 0.5.5, and to clean up the code base to be more maintainable. There may performance lost with the 1.1.5 to 2.1.1 migration since the fastpath code was removed, but the increased safety is probably worth it. See [the release notes for go-msgkack 2.1.0](https://github.com/hashicorp/go-msgpack/releases/tag/v2.1.0) for more details. I tested this by running this code, and booting up a cluster with a node also running the prior version of Nomad (before the upgrade). Before I made the changes to set the right `time.Time` option, the previous-version node would throw a bunch of time-decoding errors. After fixing the option, the node came up smoothly, even after changing leadership between them. This relies on - [ ] hashicorp/serf#705 - [ ] hashicorp/raft-boltdb#38 - [ ] hashicorp/raft#577 - [ ] hashicorp/memberlist#292 and maybe - [ ] hashicorp/net-rpc-msgpackrpc#12

Thank you @swenson! I left few comments for your consideration.

This adds the option to specify what version of the `time.Time` encoding format is desired. The default option is `false`, which preserves compatibility with the current dependency of `hashicorp/go-msgpack 0.5.5` in go.mod, but users of this library will probably want to override the the setting. While we're here, upgrade the go.mod file. I tested that this appears to work with Nomad. This needs to be updated and merged after hashicorp/memberlist#292
