block of data into the console as well as generate a large block of of output out of the console to ensure that console remains stable. This test supports all form factors including fixed and modular. On a modular system (Currently only supports Arista, but can easily be extend to to other systems), it exercises both the supervisor and the linecard console. This requires extending the related fixtures to create a LinecardConsoleConn helper that can encapsulate the console interaction on a linecard, which requires architecture specific adaptation.

Description of PR
Summary:
Fixes #21134
This test exercises the console of a SONiC Device by pushing a large block of data into the console as well as generate a large block of of output out of the console to ensure that console remains stable.
This test supports all form factors including fixed and modular. On a modular system (Currently only supports Arista, but can easily be extend to to other systems), it exercises both the supervisor and the linecard console.
This requires extending the related fixtures to create a LinecardConsoleConn helper that can encapsulate the console interaction on a linecard, which requires architecture specific adaptation.

Approach
What is the motivation for this PR?
This test verifies the stability of the serial console under load.
How did you do it?
This pushes a large block of data into the console as well as generate a large block of of output out of the console to ensure that console remains stable.
This requires extending the related fixtures to create a LinecardConsoleConn helper that can encapsulate the console interaction on a linecard, which requires architecture specific adaptation.
How did you verify/test it?
This test has been verified on Arista platform.
Any platform specific information?
Supported testbed topology if it's a new test case?
