docs: move telemetry under operations

Create a new "Operating Nomad" section of the docs where we can put reference
material for operators that doesn't quite fit in either configuration file /
command line documentation or a step-by-step Learn Guide. Pre-populate this
with the existing telemetry docs and some links out to the Learn Guide
sections.
