Improve container base image detection (#234)

* Improve container base image detection
- Improve ASP.NET project detection to work with netcoreapp2.1 applications
- Grab the target framework name and version from the project separately so we can use the vesion to determine the base image
- Updated Dockerfile generation and tye run --docker to work with different container versions based on the TFM version.
