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.

Fix alloc health with checks using interpolation Fixes an issue in which the allocation health watcher was checking for allocations health based on un-interpolated services and checks. Change the interface for retrieving check information from Consul to retrieving all registered services and checks by allocation. In the future this will allow us to output nicer messages.

// ConsulServiceAPI is the interface the Nomad Client uses to register and
// remove services and checks from Consul.
type ConsulServiceAPI interface {
consul: support canary tags for services Also refactor Consul ServiceClient to take a struct instead of a massive set of arguments. Meant updating a lot of code but it should be far easier to extend in the future as you will only need to update a single struct instead of every single call site. Adds an e2e test for canary tags.
