Issues with default data-dir post-#292

[jamtur01]

The #292 merge breaks the module if you don't use /opt/consul as the data directory.

My config hash:

  data_dir: '/var/consul'
  datacenter: 'redacted'
  encrypt: 'redacted'
  enable_syslog: true
  rejoin_after_leave: true
  log_level: INFO
  retry_join_ec2:
    tag_key: Flag
    tag_value: consul

Sorry about this, I guess I merged it prematurely.
I'll make a PR to do that last part and actually use data_dir as the root.
