[awsfirehose] Avoid using dynamic templates for flattened objects

[mrodm]

Proposed commit message

Update flattened field definitions to not create dynamic templates.

As they were previously, this dynamic template is created

  "dynamic_templates": [
    {
      "aws.firehose.parameters.*": {
        "path_match": "aws.firehose.parameters.*",
        "mapping": {
          "type": "flattened"
        },
        "match_mapping_type": "object"
      }
    }
  ],

but this definition does not match the fields under aws.firehose.parameters.

Does this change to this definition makes sense for the expected documents?

[jsoriano]

Yeah, this is probably the expected use.
