Log Message:
Update sysutils/consul to 0.8.5.

BREAKING CHANGES:

- agent: Parse values given to `?passing` for health endpoints.
- agent: The default value of `-disable-host-node-id` has been changed
  from false to true.

IMPROVEMENTS:

- agent: Added a `-disable-keyring-file` option to prevent writing
  keyring data to disk.
- agent: Added automatic notify to systemd on Linux after LAN join is
  complete, which makes it easier to order services that depend on
  Consul being available.
- agent: The `http_api_response_headers` config has been moved into a
  new `http_config` struct, so the old form is still supported but is
  deprecated.
- dns: Added support for EDNS(0) size adjustments if set in the
  request frame.
- server: Added a startup warning for servers when expecting to
  bootstrap with an even number of nodes.
- agent: (Consul Enterprise) Added support for non rotating,
  statically named snapshots for S3 snapshots using the snapshot
  agent.

BUG FIXES:

- agent: Fixed a regression where configuring -1 for the port was no
  longer disabling the DNS server.
- agent: Fix `consul leave` shutdown race.
- agent: Show a better error message than 'EOF' when attempting to
  join with the wrong gossip key.
- agent: Fixed an issue where the `Method` and `Header` features of
  HTTP health checks were not being applied.
- agent: Fixed an issue where internally-configured watches were not
  working because of an incorrect protocol error, and unified internal
  watch handling during reloads of the Consul agent.
- server: Fixed an issue where the leader could return stale data
  duing queries as it is starting up.
