health: remove "families" from alarms config

[ilyam8]

Summary

Follow-up on #14982 and part of netdata/product#3118 and #15030.

---

This PR modifies health configurations:

• removes "families: *"
• replaces the rest of the families with chart labels.

Note This PR doesn't update documentation.

---

@MrZammler we usually align all the entities, which means we need to re-align all the alarms that use "chart labels" because that's the longest entity.

I think that we can rename it to just "labels":

• one word => shorter => looks neater.
• no re-aligning needed.
• "host labels" is used very rare (only once actually), so there won't be any confusion.

Test Plan

The changes are straightforward, no manual testing is needed, just a visual review of the changes.

Hey Thiago, it's already there https://learn.netdata.cloud/docs/alerts-and-notifications/configure-alerts#alarm-line-families . Should we add something more?

I took a look and I think this is enough.
