Update WebAPI project template for beta5

[peterblazejewicz]

This commit updates WebAPI project template to one coming with beta5:

• new hosting.ini file added to project
• updated project.json
• new README.md based on current html readme document from ASP.NET
• the ValuesController renamed and moved into more proper directory structure
• the tests are updated to new content and updated structure

The tests are updated for new structure and npm tests after RGR are now passing, however I cannot restore this project:

Unable to locate System.Collections.Immutable >= 1.1.36
Unable to locate System.Reflection.Metadata >= 1.0.21
