Refactor log statements to better use log context, reduce verbosity

[jgwest]

Description:

• Move some INFO-level log statements down to DEBUG, to reduce verbosity
• Move log text to constants to in log util package
• Remove spaces from log constant names
• Remove log context from log statements when that same log context is already being logged as part of the log object via log.WithValues(...)
• Change the param order of deleteDbEntry, to move the least specific params (dbqueries, log) to the end of the function signature
