Mathieu Bultel c6cd605781 Use update_serial as an ansible variable
Use update_serial as ansible variable for being able to
override the value with CLI or ansible-playbook command line.

This should result as the following:
at the heat level:
  * if no update_serial in the roles_data is provided, the default
    value is 1
  * if update_serial is provided by the roles_data, the default value
    for the ansible var is the one in the roles_data.
  * if ansible-playbook -e update_serial=<something> , the serial value
    is the one provided by the CLI.
