.NET Client SDK Analyzers .ctor rules firing false positives

Storage triggers the following analyzer rules but I think they're false positives:

- AZC0006: The guidelines show you can have optional `*ClientOptions` for your less important ctors per https://azuresdkspecs.z5.web.core.windows.net/DotNetSpec.html#dotnet-client-ctor-overloads but the rule appears to be more strict by demanding separate overloads

- AZC0007: This is looking for `AppendBlobClientOptions` instead of `BlobClientOptions` and firing

You can repro by removing the `NoWarn`s at https://github.com/Azure/azure-sdk-for-net/blob/master/sdk/storage/Directory.Build.props#L19
