multiple group membership

[ka-mp-6765]

Can we get the option to assign multiple groups?
t.ex.

  - name: webserver001
    group: 
       - webservers     
       - debian    
       - proxmox01     

  - name: webserver002
    group: 
       - webservers     
       - ubuntu    
       - proxmox04     

  - name: syslog01
    group: 
       - debian    
       - netservers    
       - proxmox01     

this way can can see how my webservers are doing, or view all my debian servers, or everything running on proxmox01 etc etc. Very helpful when examining errors.
