A request params extractor takes a request message, extracts specific field values from
it, converts them in strings and returns them as key-value pairs, where a key is a request field
name and a value is a string representation of a field value. Nested fields should also be
extractable, in such case the "dot notation" can be used to represent a nested field name, for
example "field_name.nested_field_name".
Implementations of this interface are expected to be autogenerated.
Extracts specific fields from the request and returns them in a form of key-value
pairs, where a key is a field name and a value is a field's string representation. To represent
nested field names the "dot notation" can be used.
