[ClusterLabs] get status of each RG

[Florin Portase]

Hi Ken, 

Somehow I've manged to make it working. 

I had to use "(crm_resource -L  |grep "Resource Group:" |awk '{print
$NF}')" and after to loop through resources... 

But in the case of a stopped RG:  something like this is not so clear :
"resource rgcl0111 is NOT running"
