dictionaries of labels to be added.

For example, this configuration:

processors:
  - add_labels:
      labels:
        number: 1
        with.dots: test
        nested:
          with.dots: nested
        array:
          - do
          - re
          - with.field: mi
		

Adds these fields to every event:

{
  "labels": {
    "number": 1,
    "with.dots": "test",
    "nested.with.dots": "nested",
    "array.0": "do",
    "array.1": "re",
    "array.2.with.field": "mi"
  }
}
