[Feat]: ability to use the health management api via NC

[andrewm4894]

Problem

It would be nice if i could set up cron jobs in Netdata Cloud to orchestrate my use of the health management api in a nice and painless way.

https://learn.netdata.cloud/docs/agent/health/reference#disabling-health-checks-or-silencing-notifications-at-runtime

Description

Some way to define cron jobs or "schedules" to hit the health management api on all or a subset of nodes and have it all be run and managed easily from within netdata cloud so i dont have to roll my own solution for how im actually going to use the api.

Importance

nice to have

Value proposition

1. easier node and config management via NC

Proposed implementation
