Updated documentation, added '--no-checkout' option

[ngaranko]

I've added extra option '--no-checkout' in order to skip checkout tag step.
Problem we had is that plugin is trying to checkout tag "2.0.0-jenkins-1" which doesn't exists and we don't want to have one.

Hi, I think that you are using vdt-version in the wrong way.
Are you trying to build a package of tag 2.0.0, and are finding that vdt-version is checking out 2.0.0-jenkins-356?

Vdt-version is designed to have one to one mapping of code to packages. You can not create 2 packages with same version but the different code and you can not create 2 packages with different versions but the same code.

By accepting this pull request it WOULD become possible to create 2 packages with the sam version number, but different code. That is why I can not accept your pull request.

I think your problem can be solved in a different way.
Please provide more details on the issue you are having.
