jupiter builds stats upload (#315)

 - Improvement: At end of build upload we post statistics to the Jupiter build stats endpoint:
	- `totalSize`
	- `reusedRatio`
	- `reusedBlockCount`
	- `reusedBlockByteCount`
	- `newBlockCount`
	- `newBlockByteCount`
	- `uploadedCount`
	- `uploadedByteCount`
	- `elapsedTimeSec`
	- `uploadedBytesPerSec`
