Transform to custom dotnet template

[Simply007]

Motivation

.Net developers are used to initializing a new app by using dotnet new command. Let's make the starting point as easy as possible for them and use it as the primary getting started step instead of Use this template on Github.

Proposed solution

• Use MS docs to set up metadata for the template: https://docs.microsoft.com/en-US/dotnet/core/tools/custom-templates
• It is possible to find the inspiration on Kontent .Net Boilerplate https://github.com/Kentico/kontent-boilerplate-net/tree/master/src
• Use GitHub action CI to publish Nuget created from the template https://github.com/marketplace/actions/publish-nuget
