cannot run planner in simulated environments

I tried to run omdb nexus blueprints regenerate against omicron-dev run-all, but it failed:

$ omdb --destructive nexus blueprints regenerate
note: Nexus URL not specified.  Will pick one from DNS.

Error: generating blueprint

I think this used to work so my guess is we added something to the planner that expects boundary NTP zones (reasonable) but never added these to the simulated blueprint?

When we fix this, it would be good to add a test that:

• running the planner on a freshly set up configuration creates a blueprint with no diff against the initial blueprint (we have a similar test for non-simulated environments in the end-to-end tests)
• executing that initial blueprint works and does not change internal or external DNS (will also cover cannot execute initial blueprint in simulated environment #8222).
