Set several hostnames for cluster checks (like check_icmp can)

[MarcusCaepio]

Hi Claudio,
using this awesome plugin to check several elastic clusters in icinga2. I have both local and "cluster" services, where the local checks are configured in the host objects themself and for the cluster checks, I define a "cluster" Host object. As check_icmp can check several Hosts and alert when hosts_alive < x, this fits nice for a general host check_command. But it would be nice, if I could also set several hostnames in es_system to get the cluster state from any of my configured nodes, without the need of using an HAproxy etc. What do you think about this?

Have a nice weekend.
Cheers,
Marcus
