Support running a validation command on the destination file.

[jmkeyes]

This patch allows a user to pass an optional validate_cmd parameter to a concat resource, which in turn will run a command to validate the output of the file before the module replaces it. It follows the same semantics as the validate_cmd parameter to the file resource.

Example:

concat { '/etc/httpd/conf/httpd.conf':
  ensure       => file,
  validate_cmd => '/usr/sbin/apache2 -t -f %',
  owner        => 'apache2',
  group        => 'apache2',
  mode         => '0644'
}

This would be a great feature. However, it needs unit tests and really should have acceptance tests as well.

and it probably won't work :(

@igalic Why not? The aggregiate file generated by the script is copied into place with a file resource.

aaah. sorry, i thought that was for the fragments

@jhoblitt, Are these the tests you're looking for?

[jhoblitt]

@jmkeyes Aye! I'll give it a try as soon as I have the chance.
