* Adding support for Consul 1.4 ACL system
* Working tests
* Fixed logic gate
* Fixed logical gate that evaluate empty policy or empty list of policy names
* Ensure tests are run against appropiate Consul versions
* Running tests against official container with a 1.4.0-rc1 tag
* policies can never be nil (as even if it is empty will be an empty array)
* addressing feedback, refactoring tests
* removing cast
* converting old lease field to ttl, adding max ttl
* cleanup
* adding missing test
* testing wrong version
* adding support for local tokens
* addressing feedback
Vault will now register itself with Consul. The active node can be found using `active.vault.service.consul`. All standby vaults are available via `standby.vault.service.consul`. All unsealed vaults are considered healthy and available via `vault.service.consul`. Change in status and registration is event driven and should happen at the speed of a write to Consul (~network RTT + ~1x fsync(2)).
