The `nomad operator raft` and `nomad operator snapshot state` subcommands for inspecting on-disk raft state were hidden and undocumented. Expose and document these so that advanced operators have support for these tools.

Usage: nomad operator raft logs <path to nomad data dir>

Display the log entries persisted in the Nomad data directory in JSON

format.
|

|

This command requires file system permissions to access the data directory on
|
|
disk. The Nomad server locks access to the data directory, so this command
|
|
cannot be run on a data directory that is being used by a running Nomad server.
|

This is a low-level debugging tool and not subject to Nomad's usual backward
|
|
compatibility guarantees.
