Enable extra options in vm's status (kubectl get kvm)

[seswarrajan]

As per the current implementation, the current kvm get options only displays the kvm name and active time.
Need to extend this option more to display the following :

1. Show the last active login status
2. Show the no.of.connections

While working on this PR, extra care needed to be taken as to the implementation must support both k8s and non-k8s environment
