Documentation regarding accepted parameters for exporter

[matiasba]

There seems to be at least 5 target parameters that are not documented properly.

check-keys
check-single-keys
check-streams
check-single-streams
count-keys

The parameters are parsed here

They can be used like this:

scrape_configs:
  - job_name: 'redis_exporter'
    scheme: https
    static_configs:
      - targets:
        - redis://first-redis-host:6379
    metrics_path: /scrape
    params:
      check-keys: ["mt:*,la:*"]
      count-keys: ["mt:*,la:*"]
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: <<REDIS-EXPORTER-HOSTNAME>>:9121

It seems the parameters need to be pass as a single string separated by commas instead of a proper yaml array. If passed as an array only the last value is used.

Correct, check-keys parameters are comma separated and not using yaml.

Probably a good idea to add them to the README, can you open a PR?
