[archivist] Fix memory usage issue.

This CL fixes high memory usage in Archivist:
- Switch to correct constant for in-memory buffering.
- Switch to buffer_unordered to support out of order execution of
inspect snapshots.
- Increase snapshot limit from 2 to 4, to provide for better backfilling
and throughput.

Still need to limit overall work between archive accessors.
