Title: Build checkout ext

Extension point needs to be created for defining a custom checkout strategy. It's extremely useful in Matrix builds, where there is no need to several checkouts to be made. E.g. same source code is used for build with diff parameters, in this case it's waste of space used. Another example is using a shared drive across several build executions.
