changed the title
* Fix to explicit stop the config_manager * Add tests for chassisd run method.
Set the `config_manager` variable to `None` if we are running on a linecard and thus don't need to set up the config manager. During cleanup, the chassid service tries to clean up the `config_manager`, but the `config_manager` variable is only ever initialized if we are on the supervisor. Thus, checking if it is `None` is insufficient because this results in an `UnboundLocalError` that prevents the cleanup from succeeding on a linecard.

Description
Set the
config_managervariable toNoneif we are running on alinecard and thus don't need to set up the config manager.
Motivation and Context
During cleanup, the chassid service tries to clean up the
config_manager, but theconfig_managervariable is only everinitialized if we are on the supervisor. Thus, checking if it is
Noneis insufficient because this results in anUnboundLocalErrorthat prevents the cleanup from succeeding on a linecard.
How Has This Been Tested?
This has been tested via both the sonic-mgmt platform_tests test case
for the chassid daemon as well as the updated unit tests in this PR.
Additional Information
This is a cherry-pick of PR #347 to 202211 release branch. Note that
PR #328 is also backported to 202211 in this PR as it is required for the
unit test update to pass.
