Add support for dotnet publish

[zijchen]

Running dotnet publish will place the dacpac and all dependencies into the publish folder. Note this does not publish dacpac to databasae, please use sqlpackage for that.

Closes #447

clarifying "and all dependencies" - if I have a sqlproj with a dacpac file reference and a dacpac nupkg reference - then run dotnet publish -
is the result that the project.dacpac is placed in the output/publish folder plus the other 2 dacpacs?

That is correct.

does publish folder include database references? master dacpacs?

Yes, all references, whether they come from a project, Nuget, or direct dacpac reference get copied to publish folder.
