If a crawl is completed, the endpoint streams the logs from the log
files in all of the created WACZ files, sorted by timestamp.
The API endpoint supports filtering by log_level and context whether
the crawl is still running or not.
This is not yet proper streaming because the entire log file is read
into memory before being streamed to the client. We will want to
switch to proper streaming eventually, but are currently blocked by
an aiobotocore bug - see:
