When mutiple subnets configured in one connection thru endpoint group.
the connection name suffix shown in ipsec status is not always as 0x1
but something like 08d11cfb-dc15-43e2-aee3-c2c71e6ae8e3/1x1 and 1x2 etc.
In this patch, we get the exact connection names from the status output
and then terminate them one by one in a loop.
