Add support for LogStruct

[ndbroadbent]

Adds support for LogStruct:

• https://github.com/DocSpring/logstruct
• https://logstruct.com

Also with some compatibility for SemanticLogger PR #66. Shared patterns (both PRs use):

1. VALID_LOGGER_TYPES array - each PR adds their own type to this array
2. configure_logger_automatically - renamed from configure_lograge_automatically (with backward-compat alias)
3. logger_type configuration option with getter/setter
4. CLI --logger_type=TYPE flag
5. Conditional validation based on logger_type
6. Helper methods like lograge?, logstruct? (PR Add SemanticLogger support #66 adds semantic_logger?)

Hey @ndbroadbent thanks for the quick PR !

Since this is a more structural PR than a simple feature, and as I did with the semantic logger PR, I would want to do an extra check using the test app, can you create a branch (and a PR from it) in the test app repo that configures logstruct and makes sure all log lines are displayed in the tui?

Here's some instructions => open in new tab, the internal navigation in github is broken for comments I just realized

I got some stuff working:

I also discovered quite a few issues in logstruct that I was able to fix, so this was a really helpful exercise. And I'll probably be using log bench quite a lot, this is really cool! will open a PR for the test app

Just make sure the final output looks like this

Hmm how are you linking the actual job executions to a request ID? I think that is a bit out of scope for LogStruct (ensuring a request ID is passed with each job invocation and tying all the logs together), so I'm wondering how you've done that for log_bench?
