Support for specifying owner part 2

[doino-gretchenliev]

Modify mkdir command execution to support execution user and owner.

exec {"$name unpack":
        command => $extension ? {
          'zip'     => "mkdir -p ${target} && ${extract_zip}",
          'tar.gz'  => "mkdir -p ${target} && ${extract_targz}",
          'tgz'     => "mkdir -p ${target} && ${extract_targz}",
          'tar.bz2' => "mkdir -p ${target} && ${extract_tarbz2}",
          'tgz2'    => "mkdir -p ${target} && ${extract_tarbz2}",
          default   => fail ( "Unknown extension value '${extension}'" ),
        },
        creates => $extract_dir,
        timeout => $timeout
      }
