This allows to query a remote storage (eg. bigtable/gcs) using the logcli. It requires to provide a loki configuration files.

example of usage:

logcli query --org-id=3927 --local-config=/Users/ctovena/local-gcs.yaml {container_name="ingress-nginx"}

Example of configuration:

chunk_store_config:
limits_config:
  enforce_metric_name: false
  ingestion_burst_size_mb: 20
  ingestion_rate_mb: 10
  ingestion_rate_strategy: global
  max_global_streams_per_user: 10000
  max_query_length: 12000h
  max_query_parallelism: 32
  max_streams_per_user: 0
  reject_old_samples: true
  reject_old_samples_max_age: 168h
schema_config:
  configs:
    - from: "2018-04-15"
      index:
        period: 168h
        prefix: loki_dev_index_
      object_store: gcs
      schema: v9
      store: bigtable
    - from: "2019-10-30"
      index:
        period: 168h
        prefix: loki_dev_index_
      object_store: gcs
      schema: v11
      store: bigtable
storage_config:
  bigtable:
    instance: dev-us-central1
    project: dev
  gcs:
    bucket_name:  dev
  max_chunk_batch_size: 50

This is very handy to debug store queries.

local-config sounds a little confusing. Should we call it storage-config or store-config instead?
What do you think?
