Approach

What is the motivation for this PR?

Fix the following issue:

 def is_sonic_console(conn_graph_facts, dut_hostname):
> return conn_graph_facts['device_console_info'][dut_hostname]["Os"] == "sonic"
E KeyError: 'Os'

Signed-off-by: Longxiang Lyu lolv@microsoft.com

How did you do it?

Some lab device console information doesn't have the "Os" attribute. Let's retrieve it with an empty string as a default.

How did you verify/test it?

Run on dualtor.

Any platform specific information?

Supported testbed topology if it's a new test case?
