🐛 observation cycle cancellation

[GitHK]

What do these changes do?

Adding cancellation of observation cycle. Allows for resources to be freed and services to close faster.

NOTE: by design, the legacy dynamic sidecar scheduler, never supported this. The observation cycle will raise some unexpected errors when cancelled. 🔨🔨

NOTE: upcoming, new version of the scheduler, already comes with proper cancellation and will avoid all this mess.
