	// We want to be able to report fields which we cannot map as an
	// error so that users find typos in their configuration quickly. To
	// achieve this we use the mapstructure library which maps a a raw
	// map[string]interface{} to a nested structure and reports unused
	// fields. The input for a mapstructure.Decode expects a
	// map[string]interface{} as produced by encoding/json.
	//
	// The HCL language allows to repeat map keys which forces it to
	// store nested structs as []map[string]interface{} instead of
	// map[string]interface{}. This is an ambiguity which makes the
	// generated structures incompatible with a corresponding JSON
	// struct. It also does not work well with the mapstructure library.
	//
	// In order to still use the mapstructure library to find unused
	// fields we patch instances of []map[string]interface{} to a
	// map[string]interface{} before we decode that into a Config
	// struct.
	//
	// However, Config has some fields which are either
	// []map[string]interface{} or are arrays of structs which
	// encoding/json will decode to []map[string]interface{}. Therefore,
	// we need to be able to specify exceptions for this mapping. The
	// patchSliceOfMaps() implements that mapping. All fields of type
	// []map[string]interface{} are mapped to map[string]interface{} if
	// it contains at most one value. If there is more than one value it
	// panics. To define exceptions one can specify the nested field
	// names in dot notation.
	//
	// todo(fs): There might be an easier way to achieve the same thing
	// todo(fs): but this approach works for now.

	// There is a difference of representation of some fields depending on

	// `ID` are mapped to an ID field) the same thing does not happen between
	// CamelCase and snake_case. Since changing either format would break
	// existing setups we have to support both and slowly transition to one of
	// the formats. Also, there is at least one case where we use the "wrong"
	// key and want to map that to the new key to support deprecation -
	// see [GH-3179]. TranslateKeys maps potentially CamelCased values to the
	// snake_case that is used in the config file parser. If both the CamelCase
