Refactor of backup/restore scripts to switch form innobackupex to mysqldump tool

- Add the refactor functions and cases for mysqldump tools for DB's backups on restore script, and puppet tunning for use mysqldump as default DB backup tool

Note: we do not remove percona backups in case the user want to use it, but by default is configured to use mysql.

Fixed issue on ci.forj.io. requires resubmitting.
