Title: Add heartbeat filter

Heartbeat monitoring per host.

Generates a JSON structure that can be used to create a custom heartbeat dashboard.
The output consists of a row per host which includes the host's
last_heartbeat, last_alert and status.

This plugin also sends an alert when the heartbeat_timeout is exceeded and
supports alert throttling to reduce noise.
