What is the motivation for this PR?
Seeing failures on testbed with different hwsku's with different asic count.
In Chassis testbed, with different LC hwSKU , if one of the selected LCs have 3 asics and another LC has 2 asics, we see the below failure:

raise ValueError("Invalid asic_id '{}' passed as input".format(asic_id))
ValueError: Invalid asic_id '2' passed as input
, error:Invalid asic_id '2' passed as input
Issue is because the get_pkt_drop function takes the asic_index of the selected HwSKU or selected LC.
If the random asic_index selected is 2, and if get_pkt_drops() is called with asic_index 2 for a different LC in the testbed with 2 asics, the test fails as asic_index 2 is not present in the different LC.
How did you do it?
Fixed get_pkt_drops to go through all asic namespaces and get drop count.
This way get_pkt_drops will return packet drops for all interfaces from all namespaces.
How did you verify/test it?
Verified on packet chassis, voq chassis and single asic DUT testbed.

Any platform specific information?
Supported testbed topology if it's a new test case?
