expose doctrine:phpcr:mapping:info command in console and fix configuration templates

we seem to have missed adding this command to the console.

unsure if we need to call this a BC break. if you do not use this newly exposed command, there is no issue, but if you start using it, you must update the cli-config.php file to have the driver loaded, or you get a very uninformative fatal exception PHP Fatal error:  Call to a member function isTransient() on a non-object in /home/david/liip/symfony-cmf/doctrine/phpcr-odm/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/AbstractClassMetadataFactory.php on line 268
