+* agent: Consul 1.0 shipped with an issue where `Args` was erroneously named `ScriptArgs` for health check definitions in the /v1/agent/check/register and /v1/agent/service/register APIs. Added code to accept `Args` so that the JSON format matches that of health checks in configuration files. The `ScriptArgs` form will still be supported for backwards compatibility.
