This will allow later more gpu candidates. Note: This is an unfinished work, we keep the previous behavior for now To finish this, all algos solutions should be migrated and submitted nonces attributes stored. Its required to handle the different share diff per nonce and fix the possible solved count error (if 1/2 nonces is solved).
