Add the option to shallow clones with git

[freyes]

The new parameter used to indicate that you want a shallow clone is :depth

This is particularly useful for big repositories or trying to clone over slow connections, I'm dealing with both problems at the moment.

Another scenario where this functionality comes handy is when you're testing puppet recipes inside vagrant, for big repos this will speed up your jobs.

@niedbalski , you can, here is a usage example:

  vcsrepo { "/home/foo/bar":
    ensure => present,
    user => "www-data",
    group => "www-data",
    owner => "www-data",
    provider => "git",
    source => "git@localhost:bar.git",
    force => true,
    depth => "1"  # number of commits to clone, parameter passed `--depth` while cloning
  }

Was this notice left in accidently?

@apenney yes, I missed it while I cleaned my debugging message, I just updated the commit to remove it. Thanks for notice it.

Who can fix the bundler issue on travis?

[sodabrew]

Rebase onto just-fixed master.

[freyes]

Done, pushed commit after rebase it
