Add more telemetry to the monthly ol_dump process

[cclauss]

Add more debug information to the ol-dump process based on the lessons learned in the 2022-05-31 dumps.

1. yymm=$(date +%Y-%m) --> yyyymm=${yyyymmdd:0:7} # So we get 2022-05 instead of 2022-06
2. Log using the prefix 2022-06-01 15:25:06 [openlibrary.dump] in bash and Python to simplify grepping the logs.
   • ol-home0% docker logs -f openlibrary_cron-jobs_1 2>&1 | grep openlibrary.dump
3. More consistently log the arguments being passed.
4. Log whether or not Sentry is properly enabled.
5. Log timing of major processing steps to quickly spot which jobs are not functioning correctly.
