What this PR does / why we need it:

The current implementation bases the value used for replay_memory_ceiling only on the memory-request of the ingester Pod. This works for our "production sizes", because they all have a request. When used with size: 1x.demo it results in a memory ceiling setting of 0, which is not intended.

This results in the WAL-replay flush to run on almost each block it creates, leading to a lot of unnecessary flushes and, in the end, resulting in a very long startup time of the ingester (in the order of minutes even for a very small deployment).

This PR fixes this behaviour by providing a minimum value for the replay_memory_ceiling setting. Because we do not have any requests, this is intentionally set very low (currently at 512MiB).

Which issue(s) this PR fixes:

Fixes LOG-4840

Special notes for your reviewer:

This might just be a partial fix for the linked issue, because this only applies to users running LokiStack with 1x.demo.

    feat: Introduce `index audit` to `lokitool` (#13008)

    Adds a new `index audit` command to the `lokitool` cmd.
    The new `index audit` validates that all chunks required by a given index are available at the object storage. This is useful to validate if you're missing data after a backfill or when migrating data from one Loki instance to another.
    See `pkg/tool/audit/README.md` for usage instructions.
