Use lazy % formatting in logging functions

[OpenBagTwo]

Is your feature request related to a problem? Please describe.

A message that consistently comes up in the PyLint reports is:

W1202: Use lazy % formatting in logging functions (logging-format-interpolation)

There are, apparently, performance reasons for this suggestion, but for me, the primary advantage is that it makes tests much cleaner, e.g. 35854ba#diff-a908114b22e34b7043cbe4670c94a557cff7431a0818027a255607239c96cdb7

The secondary advantage comes when it's time to actually capture and utilize logs (#129), as having the dynamic values separated from the log boilerplate itself simplifies the parsing required.

Describe the solution you'd like

1. Do a full repo search for logging messages
2. Where possible, implement dynamic elements of log messages with lazy-formatted arguments
3. Update tests where possible to check args instead of the formatted message

Describe alternatives you've considered

Not doing this

Additional context

I could have sworn that doing this would break any tests, and that caplog[i].message was just the placeholders without the arguments, but if that was ever the case, it appears to be no longer. 🤷
