The `nomad service info` command doesn't support using a wildcard namespace with
a prefix match, the way that we do for many other commands. Update the command
to do a prefix match list query for the services before making the get query.
Fixes: #18831
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.
