Approach

What is the motivation for this PR?

We need a flag to mark that DUT is under end to end test.
sonic-net/sonic-utilities#3102
db migrator needs to detect DUT is running in end to end test.

How did you do it?

Create /etc/sonic/mgmt_test_mark with fixture.

How did you verify/test it?

Run end to end test, and check /etc/sonic/mgmt_test_mark.

Any platform specific information?

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

I could not find any code related the usage of the file "disable_loganalyzer_mark". So I could not really understand "What is the motivation for this PR?"

sonic-net/sonic-utilities#3102
db migrator will use this flag to detect loganalyzer is disabled in end to end test.

Updated with simplified design.

You can use duthosts.shell as well. It will automatically dispatch the shell module to each duthost.
With module_ignore_error should be enough. No need to catch other exceptions. When the DUT is unreachable, the exception will be handled by other functions.
