Clean up logging / tracing logger output

[turadg]

What is the Problem Being Solved?

While developing for MN-1 we've accumulated a lot of log output. We won't want all of that in production.

Description of the Design

We can't simply condition on a prod vs dev environment variable because SES locks down.

We'll have to be judicious in what we log at all and have practices for enabling logging in dev that can't impact prod. For longer term solution see #1318

Security Considerations

Log output can provide information for attacks.

Test Plan

Look at log output in dev net.

[Tartuffo]

We should consistently use structured logging.

Scaling Considerations

Each trace(...) call is a console.log(...) which is implemented as a vat-to-kernel syscall. So keeping these turned on has some performance impact. I don't have any reason to believe it would be large.

Meanwhile, having them turned on provides a certain form of observability.
