What do I have to update for ChangeLog.md? My service does not have a src/{{SERVICE}}/{{SERVICE}}/ path, so where would the ChangeLog.md file go?

Some changes are required

@dolauli Do all CredScan checks have to pass? Or can CredScan checks fail if they are false positives?

Some of the tests are skipped. Is that expected?

@dolauli Yes, there are some cmdlets that are not yet fully supported, so these wouldn't return expected output at this time. Two of these partially supported cmdlets require using a valid storage key which we wouldn't want in the repo. There are a few other cmdlets that could still be tested. I will create tests for those soon and push them. Thanks.
