Publishing Microsoft.DataApiBuilder nuget to Nuget.org

[abhishekkumams]

Why make this change?

• Closes Publish NuGet package www.nuget.org #1032
  • To make the NuGet package available via www.nuget.org before public preview.

What is this change?

• Added a new build pipeline task to publish the nuget package to external feed nuget.org.
• This task will only run when the pipeline runs with isNugetRelease set to true.

How was this tested?

• Passing Pipeline
• Going to Nuget.org to verify
• Steps:
  1. Created a test package (It's a demo package which only prints hello world).
  2. Added it to the repo and commented out all the build steps other than (code signing, and publishing) to speed things up.
  3. Successfully published it through ADO pipeline with ID Microsoft.DataApiBuilder.Test, and I was able to successfully publish to nuget.org. Link: https://www.nuget.org/packages/Microsoft.DataApiBuilder.Test/

Updates

1. Facing issue with Reserved Namespace, Microsoft.DataApiBuilder.*, due to which we are unable to upload package with ID Microsoft.DataApiBuilder, whereas Microsoft.DataApiBuilder.Test works fine. There is an ongoing mail thread to update the regex for reserved namespace given to DataApiBuilder. Once we get an update on that I will update this PR.

Is this page public? do we want this published prior to announcement of public preview?

Yes, this page is public. But, we have only uploaded the test package which contains nothing.

Now that the regex for the reserved prefix has been modified, LGTM after resolving the comments.
