Modified the way fluentd configures rsyslog

Fluentd makes rsyslog to send the logs to fluentd locally.
This configuration was create within the puppet-tripleo,
mounting the /etc/rsyslog.d/ directory on the fluentd
container. This generates an issue when is deployed on
RHEL BZ #1701726.

This patch aim to fix it.
 - The /etc/rsyslog.d directory is no longer mounted
 on the fluentd container.
 - The rsyslog configuration was moved to the host_prep_tasks.
