This change allows the client HTTP and the server HTTP, Serf and
RPC health check names within Consul to be configurable with the
defaults as previous. The configuration can be done via either a
config file or using CLI flags.
Closes#3988
Since I was already fixing consul's tls handling in #2645 I decided to
update consul/api and pre-emptively fix our tls handling against the
newest consul/api behavior. consul/api's handling of http.Transports has
improved but would have broken how we handled tls (again).
This would have made for a nasty surprise the next time we updated
consul/api.
The source of truth is the local Nomad Agent. Any services not local that
have a matching prefix are removed. Changed services are re-registered
and missing services are re-added.
There were conflicting directives previously, both consul.addr and
consul.address were required to achieve the desired behavior. The
documentation said `consul.address` was the canonical name for the
parameter, so consolidate configuration parameters to `consul.address`.
Flattening and normalizing the various Consul config structures and
services has led to an import cycle. Break this by creating a new package
that is intended to be terminal in the import DAG.
