Add toolkit project, make dotnet tool

[boma96]

The toolkit is added to the project.
Beside that following things are done as well:

• Class namespaces are adjusted, using statements fixed and unnecessary usings are removed
• Classes corresponding to features we do not want currently (dllscrapper and documentation) are removed
• Code is slightly modified in order for the tool to be runnable
  • Tool assumed that classes start with prefix consisting of capital letters (e.g. UTIL_, DB_, etc.)
• Project is dotnet tool, i.e. it can be invoked with dotnet conductorsharp command

Currently, the tool works only with version 2 of the conductor. We have to think through how to adapt tool for the Sp1ne project.

We could remove some of the repetitive code from the old codebase with this PR before moving on to refactoring. (Only the things that don't require a lot of effort and do not affect functionality).

There was a lot of code that was thrown together by myself and other developers and which we would rather forget about :)

There are also some conflicts to resolve
