Improve discoverability of nuget packages

[CristianAmbrosini]

The search "sonar dotnet" only reports the scanner, whereas "sonar" also returns the CSharp analyzer in the first position.
Adding more tags would help discoverability on nuget.org.

LGTM. However, I found this, which claims that we no longer need the .nuspec file. Did you look into that?
Right now, the tags are duplicated, which is not optimal.

I was not able to find more references. Anyway, nuspec tags where already there, I just extended the list. I think we can keep it like this for now, the duplication (if any) should not be that big of a deal anyway in my opinion
