Current group export API rate limits are a bit too restrictive for this kind of export, since when performing Bulk Import we need to be able to initiate multiple exports, as well be able to download a larger amount of ndjson files (comparing to Import/Export 1 tar.gz file containing everything). Add new type of rate limit to application rate limiter with greater figures. I don't think we need to make these figures configurable (at least for now), since primary goal of this API is to support Bulk Imports.
