Refactor Consul Syncer into new ServiceClient Fixes #2478 #2474 #1995 #2294 The new client only handles agent and task service advertisement. Server discovery is mostly unchanged. The Nomad client agent now handles all Consul operations instead of the executor handling task related operations. When upgrading from an earlier version of Nomad existing executors will be told to deregister from Consul so that the Nomad agent can re-register the task's services and checks. Drivers - other than qemu - now support an Exec method for executing abritrary commands in a task's environment. This is used to implement script checks. Interfaces are used extensively to avoid interacting with Consul in tests that don't assert any Consul related behavior.

Client watches for allocation health using task state and Consul checks This PR adds watching of allocation health at the client. The client can watch for health based on the tasks running on time and also based on the consul checks passing.

Implement DriverNetwork and Service.AddressMode Ideally DriverNetwork would be fully populated in Driver.Prestart, but Docker doesn't assign the container's IP until you start the container. However, it's important to setup the port env vars before calling Driver.Start, so Prestart should populate that.
