inspect: naming of process and parameters is confusing/unintuitive

[bossie]

I'm not sure why this process isn't simply called log because it doesn't inspect, it logs.

Its parameter code is also far from obvious. It acts as a label for a bunch of log entries that belong together so why not just name it label instead?

Here's some context: https://github.com/Open-EO/openeo-processes/pull/310

• There's already process called log (logarithm): https://processes.openeo.org/#log
• code (and the other parameters) are aligned with how the fields are named in the API responses.
