Arcade depends on the deprecated WindowsAzure.Storage package

The WindowsAzure.Storage package is deprecated and should be replaced with Azure.Storage.Common: https://www.nuget.org/packages/WindowsAzure.Storage

https://github.com/dotnet/arcade/blob/0b89b3c809549f07eb52dfdd62c1173ad6b4c460/eng/Versions.props#L108-L110C6

The library is currently used in couple of places in the repo and is undesirable for another reason: It brings in the entire netstandard1.x dependency graph (which includes vulnerable packages). By replacing it, we don’t need to manually bump vulnerable package versions anymore.

We (dotnet/runtime, dotnet/corefx, dotnet/coreclr and dotnet/core-setup) don’t use these tools anymore. I don’t know the history behind them but I would be surprised if they are still used. Based on https://github.com/dotnet/arcade/pull/289 it sounds like those were used for the mirrored folders between the repos. We don’t do that anymore.

The only project I see using it is https://github.com/dotnet/arcade/blob/main/src/Microsoft.DotNet.GitSync.CommitManager/Microsoft.DotNet.GitSync.CommitManager.csproj#L19

I don’t believe this tool is maintained by dnceng as it was brought in from buildtools by corefx folks. The tool is not published anywhere. The fact that the only changes we have seen in this area are playing whac-a-mole with component governance, and that it was related to the old maestro in the old corefx world makes me think this code should be deleted along with the other project mentioned in https://github.com/dotnet/arcade/blob/main/Documentation/GitSyncTools.md
