[PATCH v6 compass-ci 2/2] lib/es_query.rb: parse es_result to a Hash result - Compass-ci

7 Jan 2021

[why]
make es result more easy access.
[example]
  input:
    es_result =
      [{"key"=>"build-pkg",
        "doc_count"=>354526,
        "all_job_state"=>
         {"doc_count_error_upper_bound"=>0,
          "sum_other_doc_count"=>0,
          "buckets"=>
           [{"key"=>"failed", "doc_count"=>5708},
            {"key"=>"finished", "doc_count"=>1033},
            {"key"=>"incomplete", "doc_count"=>204},
            {"key"=>"submit", "doc_count"=>136},
            ...
output:
    result_hash =
      {"build-pkg"=>
        {"failed"=>5708,
         "finished"=>1033,
         "incomplete"=>204,
         "submit"=>136,
         "OOM"=>11,
         "post_run"=>2},
       "cci-depends"=>
        {"finished"=>1785,
         "failed"=>675,
         ...
