* agent: Serf snapshots no longer have the executable bit set on the file. [GH-2722]
* cli: Standardized handling of CLI options for connecting to the Consul agent. This makes sure that the same set of flags and environment variables works in all CLI commands (see https://www.consul.io/docs/commands/index.html#environment-variables). [GH-2717]
* cli: Updated go-cleanhttp library for better HTTP connection handling between CLI commands and the Consul agent (tunes reuse settings). [GH-2735]
* cli: The `operator raft` subcommand has had its two modes split into the `list-peers` and `remove-peer` subcommands. The old flags for these will continue to work for backwards compatibility, but will be removed in Consul 0.9.
