From: Boyuan Zhang <boyuan.zhang@xxxxxxx>
For vcn 4_0_3, add ip_block for each vcn instance during discovery stage.
And only powering on/off one of the vcn instance using the
instance value stored in ip_block, instead of powering on/off all
vcn instances. Modify the existing functions to use the instance value
in ip_block, and remove the original for loop for all vcn instances.
v2: rename "i"/"j" to "inst" for instance value.
