Background

@leftwo helped identify an issue where the ServiceManager attempts to create a service which already exists because it failed to identify that one was already running, based on the name. This resulted in a "DLPI link error", as the zone management logic tried to re-allocate an in-use IP address.

What this patch does

  • Refactors ServiceManager to be slightly easier to test
  • Fixes the prefix matching issue (it now checks for the existence of "oxz_my_svc" for a service named "my_svc", which is what the zone is actually named).
  • Adds a regression test for this issue, as well as tests for a handful of other basic behaviors.

This is simply a refactor to make accessing this information easier from elsewhere

Providing the config_path as an optional argument makes this much safer to test.
