bug: Post release fixes for Reliability (#893)

Address a number of post landing concerns:

* Fix the `garbage_collect` method to use the correct Redis table
* Have redis connection report to error logging (these are not service
critical errors, since they relate to reporting)
* Make some of the logging messages more consistent and easier to read.
