MetadataCollection and Indexer: fix the concurrency adjustment

In the previous implementation the concurrency was descreased with each
chunk so after log2(initial_concurrency) chunks it was going down to 1
no matter if there were any errors or not.

The current implementation:
* descreases concurrency only if sleep-inducing errors were encountered
  while processing the last chunk
* increases the concurrency up to original level if no sleep-inducing
  errors were encountered while processing the last chunk
