support multiple filters for the same tag

[rmacian]

currently I have chained filters and seems is not supported by the module. I only get the last filter defined on my config files. Example from the fluentd documentation:

fluentd::configs:
  'test.conf':
     config:
       filter:
         tag_pattern: foo.bar
         type: grep
         regexp1: message
       filter:
         tag_pattern: foo.bar
         type: record_transformer
         record:
           hostname: "#host"

output:

since yaml does not allow duplicate keys, there should be an alternative method
