Dynamic templates allow to define mapping templates that will be applied
when dynamic introduction of fields / objects happens.
IMPORTANT: Dynamic field mappings are only added when a field contains
a concrete value -- not `null` or an empty array. This means that if the `null_value` option
is used in a `dynamic_template`, it will only be applied after the first document
with a concrete value for the field has been indexed.
For example, we might want to have all fields to be stored by default,
or all `string` fields to be stored, or have `string` fields to always
be indexed with multi fields syntax, once analyzed and once not_analyzed.
