kvm: Maybe extend monitoring for VMs

[markuslf]

Is your feature request related to a problem? Please describe.

Using virsh:

    cpu-stats                      show domain cpu statistics
    domblkstat                     get device block stats for a domain
    domifstat                      get network interface stats for a domain
    domstats                       get statistics about one or multiple domains
    nodecpustats                   Prints cpu stats of the node.
    nodememstats                   Prints memory stats of the node.

Getting all VMs: virsh list

Might improve identifying source of some problems (on host/node or in VM/domain). Could be done in separate check plugins.
