[REQUEST] Runtime Host Tags

[jordan-rash]

I would like to be able to create tags on the host at runtime.

Something along the lines of
wash host <host-id> my:tag

This would be a powerful way to start tuning the host without restart. Currently, a problem I have is that if I forget to add a tag/label to the host, it requires a restart of the host.

I love this idea 🙌

I think we'll want some more technical details ironed out:

• when you say "tags", do you mean the existing host labels, or a new, separate set of metadata?
• how will the host receive updates?
  • presumably a new topic on the control interface?
  • will the payload be treated as a full replacement, or an "upsert"?

By tags, I mean host labels (my mistake)

I don't know how the host should best receive them, but I do think they should be an insert and not a replace.

wash host add-label <host-id> my:tag
wash host del-label <host-id> my

@jordan-rash check out #780 and let me know if you have any feedback! Once the host/control interface supports this API, we can add it to wash pretty easily

@jordan-rash bump?

#780 looks great to me
