What this PR does:
This PR simplifies internals of
SpreadMinimizingTokenGenerator: it removes logger, slice with zones, parsing of instance when computing previous instance.These changes make it easier to reuse this token generator in partitions ring code (https://github.com/grafana/dskit/compare/partitions-ring branch).
