Cloud Manufactory Heartbeat Control

Allows you to fine-tune the WordPress Heartbeat API frequency and behavior: * Pause the Heartbeat API (useful for debugging). * Decrease Heartbeat API frequency (useful when having performance issues on the site). * Automatically decreases the frequency when the site is having performance issues (useful for mitigating attacks). * Automatically decreases the frequency when the last heartbeat ajax call failed (useful for helping the server bounce back). * Allows you to manually control the frequency.
