Create group construct for hosts

[rkelleyrtp]

Is your feature request related to a problem? Please describe.
When adding servers to LXDMosaic, it would be very helpful/useful to create a group that contains the hosts. In my environment, we have three "sets" of LXD Servers: Admin Servers, QA Servers, and Production Servers. Currently, each server is added as an individual server in the Standalone Hosts list. It would be very helpful to create a Group for each server type. Then, the servers will be placed in the appropriate group (maybe via tag?)

Today:
Standalone Hosts
--> Admin Server 1
--> Admin Server 2
--> Admin Server 3
--> QA Server 1
--> QA Server 2
--> QA Server 3
--> Prod Server 1
--> Prod Server 2
--> Prod Server 3

In a grouping format:

Standalone Hosts

Group: Admin
--> Admin Server 1
--> Admin Server 2
--> Admin Server 3

Group: QA
--> QA Server 1
--> QA Server 2
--> QA Server 3

Group: Prod
--> Prod Server 1
--> Prod Server 2
--> Prod Server 3

By default, each standalone server could be in it's own group.

I see the need for this but its more complicated than it sounds (and introduces another level of loops).

Its not a no but I cant slide this into the next release 😄

Migrating to "discussions" because its not a bug fix and is more "big picture"

Thanks
