repair + compact: Improved logging for easier future debug purposes.

This is based on my experience while debugging https://github.com/prometheus/prometheus/issues/3943.

I needed to deduct few things, and all that would be just bit easier with these two logs:
- new block's ULID on each compaction.
- actual list of Blocks (ulid + time range) on Prometheus startup (easy to log that while repairing blocks).

We don't really need blocks that takes part in compaction - that can be deducted easily based on time ranges of blocks we have currently in system.

What do you think?
