Log levels

Eventing log files are not helpful enough at INFO and unusably verbose at debug and trace. The team must visit each log line and:

1. Log only useful information at INFO level
2. Log more info at DEBUG level but not so much that it can't be turned on in production
3. Log step-by-step of what the product is doing at TRACE level

Notes:
In #1 – there are recurring messages that convey no useful info. These need to be suppressed until the content changes
In #2 – we need to reduce verbosity. developers should be able to turn on debug during development and admins in production if trouble arises
In #3 – some parts of code don't have enough logs. we need to add more trace logging
