[why] get multi-field aggregation count for overview of report page.

[input]: fields, query_items (optional for query_items, default no scope limitation)

[example] input: fields = ['suite'] query_items = { 'os' => 'openeuler' } output: [{"key"=>"build-pkg", "doc_count"=>186214}, {"key"=>"cci-depends", "doc_count"=>1230}, {"key"=>"iperf", "doc_count"=>1103}, {"key"=>"spinlock", "doc_count"=>1000}, {"key"=>"cci-makepkg", "doc_count"=>949}, {"key"=>"iperf-walk-os-test", "doc_count"=>474}, {"key"=>"bisect", "doc_count"=>381}, ...

input: fields = ['suite', 'job_state'] query_items = { 'os' => 'openeuler' } output: [{"key"=>"build-pkg", "doc_count"=>186227, "all_job_state"=> {"doc_count_error_upper_bound"=>0, "sum_other_doc_count"=>0, "buckets"=> [{"key"=>"failed", "doc_count"=>3830}, {"key"=>"finished", "doc_count"=>803}, {"key"=>"incomplete", "doc_count"=>196}, {"key"=>"submit", "doc_count"=>136}, ...

input: fields = ['os', 'os_version', 'job_state'] query_items = {} output: [{"key"=>"openeuler", "doc_count"=>193287, "all_os_version"=> {"doc_count_error_upper_bound"=>0, "sum_other_doc_count"=>0, "buckets"=> [{"key"=>"20.03", "doc_count"=>191789, "all_job_state"=> {"doc_count_error_upper_bound"=>0, "sum_other_doc_count"=>0, "buckets"=> [{"key"=>"failed", "doc_count"=>3909}, {"key"=>"finished", "doc_count"=>2401}, {"key"=>"incomplete", "doc_count"=>300}, {"key"=>"submit", "doc_count"=>136}, {"key"=>"OOM", "doc_count"=>23}, {"key"=>"post_run", "doc_count"=>1}]}}, {"key"=>"20.03-SP1", "doc_count"=>904, "all_job_state"=> {"doc_count_error_upper_bound"=>0, "sum_other_doc_count"=>0, "buckets"=> [{"key"=>"failed", "doc_count"=>641}, ...
