Emilien Macchi d86025593b Handle undercloud upgrades via host_prep_tasks
Using host_prep_tasks interface to handle undercloud teardown before we
run the undercloud install.
The reason of not using upgrade_tasks is because the existing tasks were
created for the overcloud upgrade first and there are too much logic
right now so we can easily re-use the bits for the undercloud. In the
future, we'll probably use upgrade_tasks for both the undercloud and
overcloud but right now this is not possible and a simple way to move
forward was to implement these tasks that work fine for the undercloud
containerization case.

Workflow will be:
- Services will be stopped and disabled (except mariadb)
- Neutron DB will be renamed, then mariadb stopped & disabled
- Remove cron jobs
- All packages will be upgraded with yum update.

# NOTE: We're adding the log redirection here, even though should
# already be part of the options. This is because the redirection
# via the options is not working and ends up being passed as a
# parameter to the memcached command (which it silently ignores).
# Thus the need for the explicit redirection here. The redirection
# will be removed from the $OPTIONS, which is done via the puppet
# module, but we'll only be able to do this once the following pull
# request merges: https://github.com/saz/puppet-memcached/pull/88
