Aliaksandr Valialkin aadbd014ff all: add native format for data export and import
The data can be exported via [/api/v1/export/native](https://victoriametrics.github.io/#how-to-export-data-in-native-format) handler
and imported via [/api/v1/import/native](https://victoriametrics.github.io/#how-to-import-data-in-native-format) handler.
