Pathfinder `dryrun` mode: showing what queries are created from the "template-generation"

I think it'd be helpful to have a feature similar to the dryrun parameter (ref, issue) for Pathfinder.

I imagine:

preferably a parameter we can set in the POST query parameters (dryrun or caching both work this way). That's better than an environ variable set at startup (INSTANCE_ENV).
Won't fully execute pathfinder mode
Instead, once the categories of the starting nodes are known...BTE constructs the 3 templates/queries it's going to run for pathfinder. Return info on what those 3 queries are in a TRAPI response (in logs) AND console logs
Ideally, give this info in a nicer format. Current format of execution plan in console logs looks like this:

@tokebe Anything to add? Particularly on urgency? I think this would be useful right now (aka do ASAP) but it's also fine to have this later...

@rjawesome @NeuralFlux Jackson mentioned that one of you two could pick this issue and self-assign.
