Allow to change crontabs scheduling

[Emilien Macchi]

TripleO configure Nova, Keystone, Cinder and Heat with some crontabs that help to cleanup the database over time.

The scheduling is not something we can configure now from THT but it would be nice to do it, some clouds might need to run the crons more often than the daily schedule (default).

    Enabling until_complete to be configured dynamically

    Adding to THT the cabability of configuring until_complete
    in the archive job.
    This will be a boolean flag to clean all the deleted instances.
