[sfputil] Firmware download/upgrade CLI support for QSFP-DD (#1947)

[CliveNi]

What I did

• Checking that the running image is switched or not after CDB_run during firmware upgrade process.

How I did it

• Call api.get_module_fw_info() for checking the running and committed image are difference.

How to verify it

• Run sfputil firmware upgrade with transceivers of different vendor.

@CliveNi Could you please upload UT logs?.

Adding unit test for new function, disabling a test condition in commit due to it will spend around 1min, it is enabled when capturing log. This disabled condition will reduce around 10% coverage. Is it needed to cover the "NotImplementedError" exception? It will cause coverage less than threshold.

Some environment issues cause 2 unrelated functions failure in attached UT log, it still exists even if checkout to master in my environment. sfputil_test-results.txt
