This PR adds support for configuring `proxy.upstreams[].config` for
Consul Connect upstreams. This is an opaque config value to Nomad -
the data is passed directly to Consul and is unknown to Nomad.
The service registration client name was used to provide a
distinction between the service block and the service client. This
however creates new wording to understand and does not match the
CLI, therefore this change fixes that so we have a Services
client.
Consul specific objects within the service file have been moved to
the consul location to create a clearer separation.
This PR adds the common OSS changes for adding support for Consul Namespaces,
which is going to be a Nomad Enterprise feature. There is no new functionality
provided by this changeset and hopefully no new bugs.
