Parameters for index HTML-page output with S3-bucket or S3-subdir content for `Get object` request
Parameters for index HTML-page output. Activates if `GetObject` request returns `not found`. Two
index page modes available:
* `s3` mode uses tree service for listing objects,
* `native` sends requests to nodes via native protocol.
If request pass S3-bucket name instead of CID, `s3` mode will be used, otherwise `native`.
