Add pre step to change counterpoll port interval to 2000 in golden config (sonic-net#21583)

Added a step to update the counterpoll port interval to 2000 as agreed, to improve slowness observed in nexthop group and member programming
This is a WA and it should be reverted after SAI implement a new feature
to optimize the counter polling
