change some mysql tables and columns character sets, this is close to patch at mantis 8707, but that is not correct. This should have no impact on current dbs. Many of those are now too large to do this change automaticl,, but they should. Some columns as utf8 (4 bytes in future) are pure waste of space, in fact some are used as indexes and can violate max index size. Namelly on groups V2, reason why we are forced to use utf8mb3 mostly likely to be dropped by new mysql/maria versions
