Simple grouping for Monitor ping + query pings #2566

Describe your feature request:
Given a possibility to create a group identified by just it's name and a section where you can manage the belonging domains to such group/collection. Given this the Monitor ping interface would become more like a list of groups and domains as its children. Like:

-> Group 1 ---------------------------------------------------- [quick statistics] [open/close arrow]
    - example.com
    - example.org
    - etc.

that can be opened or closed.

As a second inclusive feature it would be nice to be also able to add pings against full query paths and give a more descriptive "Name" to each ping, something similar to what I can do in this android app:

I'm open to sponsoring this feature request, just let me know to what it would amount.
