Add option to give warning instead of failing the build if coverage is below threshold

[roostaamir]

• This will enable the option to choose if the build should fail when the coverage is below the threshold or just give a warning about it
• Based on the initial idea that started here: Add possibility to give warning when coverage is below the threshold instead of just failing the build #701

To the reviewer:

I need a bit of help to decide where to write tests for the new functionality. Could you please give me a suggestion about where would be the best test project to write test for this newly introduced parameter?

Thanks in advance

@dotnet-policy-service agree

Hi again

Are there any updates about comments or reviews on my PR?

[Bertk]

Thank you for the contribution.

Maybe an additional test in DotnetTool.cs should verify the new command line option.

By the way, I would use bool ThresholdWarn instead of enum ThresholdAction.

Unfortunately, I do not have the PR approve permission. @MarcoRossignoli, @daveMueller Could you please review this PR.
