feat: support publishing measurements to services

[reubenmiller]

Proposed changes

Add support for publishing measurements to services on the main and child devices:

Task list:

• Implementation in Rust to publish measurements to services on main device
• Implementation in Rust to publish measurements to services on child devices
• System tests to verify publishing of all telemetry types (measurements, events and alarms) to services on the main and child devices

Types of changes

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Improvement (general improvements like code refactoring that doesn't explicitly fix a bug or add any new functionality)
• Documentation Update (if none of the other choices apply)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
