Multiple fixes

- Update apt default packages to include dnsutils
- Update the consul task to set up dns resolution through consul and
  systemd-resolved
- Update the consul server config file to auto join hostnames instead of
  IP addresses, this makes the configuration for the playbook much
  easier
- Add a docker task to install docker (works on arm devices also)
- Updates the hashicorp apt role to allow arm devices to pull from the
  correct upstream repo
