Remove smartagent collectd/protocols monitor

[Copilot]

Pull request overview

Removes the deprecated Smart Agent monitor collectd/protocols from the embedded SignalFx Agent monitor set, aligning with the end of its deprecation period and steering users to the hostmetrics network scraper replacement.

Changes:

• Deleted the collectd/protocols monitor implementation, templates, and generated metadata.
• Unregistered the monitor from Linux module imports so it’s no longer available at runtime.
• Added a breaking-change changelog entry documenting removal and the recommended replacement.
