Output last commit when using Git.clone() or Git.checkout()

[nodeg]

A nice addition would be to output the last commit when using Git.clone() or Git.checkout() from the repo that is used. In Jenkins for example, we do also get the last commit from the pipeline repository (see Commit message below):

Since we use terracumber to e.g. clone sumaform, it would be nice to also have the last commit message printed out.
