What this PR does:
Allowing configuring different strategies to fetch block IDs from object store, similar to thanos-io/thanos#7134.
Thanos changed its block listing strategy in thanos-io/thanos#6474 which iterates the whole bucket. This can be extremely slow in some object store implementation. For example, when bucket versioning is enabled in S3, it is very slow to iterate the whole bucket. This impacts Thanos as well as Cortex 1.16.0 release.
In thanos-io/thanos#7134, Thanos reverts its block listing strategy back to the original one to avoid iterating the whole bucket. Thus, exposing the same configuration in Cortex and make the default configuration
Concurrent, which is the old working behavior.Additionally, put the bucket index based block IDs fetcher introduced in #5681 a block listing strategy as well and it is only used in Compactor. Before this change, this block IDs fetcher is always enabled when bucket index is turned on in compactor. This feature can have some downside of delayed compaction since bucket index might have delay. Putting it under a FF to allow users to choose whether to use this feature or not.
