lib/promscrape/discovery/nomad: follow-up after 48f371a46c
- Remove undocumented `username` and `password` config options from `nomad_sd_config`.
  TODO: probably, remove these options from `consul_sd_config` too?
  These options exist there for backwards compatibility purposes.

- Add __meta_nomad_service_alloc_id and __meta_nomad_service_job_id meta-labels
  These labels contain AllocID and JobID fields for the discovered Nomad services.

- Various typo fixes.
