Need to expose the atrtribute's pcInstance value same as perfcounter's instance value dynamically.

[hiralm18]

We have section like this and need to expose instance value in pcInstance value
object: "Network Interface"
instances: "*"
counters:
- name: "Packets Received Discarded"
metric: perfmon_network_interface_packets_received_discarded
attributes:
pcCategory: "Network Interface"
pcName: "Packets Received Discarded"
pcInstance: "${instance}"

e.g: instance="Intel[R] Wi-Fi 6 AX201 160MHz",pcCategory="Network Interface",pcInstance="" need to show "Intel[R] Wi-Fi 6 AX201 160MHz" this in pnInstance also.
