What this PR does:
When using minimize spread token strategy, there is a chance that multiple ingesters would have duplicated tokens if they are joining the ring around the same time.
The fix here is to pick multiple token candidates with largest distance and pick one to split based on instance name hash to avoid multiple instances got exactly same token.
Which issue(s) this PR fixes:
NA
